Switching from using list of BytesReference to real SortBuilder list in
SearchSourceBuilder, TopHitsAggregatorBuilder and TopHitsAggregatorFactory.
Removing SortParseElement and related sort parsers.
We can be better at checking `buffer_size` and `chunk_size` for S3 repositories.
For example, we know that:
* `buffer_size` should be more than `5mb`
* `chunk_size` should be no more than `5tb`
* `buffer_size` should be lower than `chunk_size`
Otherwise, setting `buffer_size` is useless.
For the record:
`chunk_size` is a Snapshot setting whatever the implementation is.
`buffer_size` is an S3 implementation setting.
Let say that you are snapshotting a 500mb file. If you set `chunk_size` to `200mb`, then Snapshot service will call S3 repository to snapshot 3 files with the following sizes:
* `200mb`
* `200mb`
* `100mb`
If you set `buffer_size` to `100mb` (AWS maximum size recommendation), the first file of `200mb` will be uploaded on S3 using the multipart feature in 2 chunks and the workflow is basically the following:
* create the multipart request and get back an `id` from AWS S3 platform
* upload part1: `100mb`
* upload part2: `100mb`
* "commit" the full upload using the `id`.
Closes#17244.
We lost some accounting code in the translog recover code during refactoring
which triggers a very rare assertion. If we fail on a recovery target with an
illegal mapping update (which can happen if the clusterstate is behind), then
we miss to rollback the # of processed ops in that batch and once we resume
the batch we trip an assertion that the stats are off.
This commit brings back the code lost in 8bc2332d9a
and improves the comment that explains why we need this rollback logic.
Now that string has been splitted into text and keyword, we use text as a
dynamic type when encountering string fields in a json document. However
this does not play well with existing templates that look like
```
{
"mapping": {
"index": "not_analyzed",
"type": "{dynamic_type}"
},
"match": "*"
}
```
Since we want existing templates to keep working as much as possible in 5.0,
this commit adds a hack to dynamic templates so that elasticsearch will create
a keyword field if the `index` property is set and is either `no` or
`not_analyzed`, similarly to what was done in #16991.
While this will make upgrades easier, we still need to figure out a way to
allow users to create keyword fields when using dynamic types.
The fielddata settings in mappings have been refatored so that:
- text and string have a `fielddata` (boolean) setting that tells whether it
is ok to load in-memory fielddata. It is true by default for now but the
plan is to make it default to false for text fields.
- text and string have a `fielddata_frequency_filter` which contains the same
thing as `fielddata.filter.frequency` used to (but validated at parsing time
instead of being unchecked settings)
- regex fielddata filtering is not supported anymore and will be dropped from
mappings automatically on upgrade.
- text, string and _parent fields have an `eager_global_ordinals` (boolean)
setting that tells whether to load global ordinals eagerly on refresh.
- in-memory fielddata is not supported on keyword fields anymore at all.
- the `fielddata` setting is not supported on other fields that text and string
and will be dropped when upgrading if specified.
Currently, both Gsub and Grok parse regex strings during
Pipeline creation. Thrown parsing exceptions were leaking out, this
commit wraps those exceptions in ElasticsearchParseExceptions.
This commit mocks the value of rlimit infinity in the max size virtual
memory check test. This is to avoid attempting to load the native C
library during the test on Windows which would lead to a permissions
violation (the native C library needs to be loaded before the security
manager is setup).
Archive cluster level settings if unknown or broken
We already archive index level settings if we find an unknown or invalid/broken
value for a setting on node startup. The same could potentially happen for persistent
cluster level settings if we remove a setting or if we add validation to a setting that
didn't exist in the past. To ensure that only valid settings are recovered into the cluster
state we archive them (prefix them with `archive.` and log a warning. Tools that check the
cluster settings can then warn users that they have broken settings in their clusterstate that
got archived.
This commit adds a bootstrap check on Linux and OS X for the max size of
virtual memory (address space) to the user running the Elasticsearch
process.
Closes#16935
Currently if you run an `exists` query on an object, it will resolve all sub
fields and create a disjunction for all those fields. However the `_field_names`
mapper indexes paths for objects so we could query object paths directly.
I also changed the query parser to reject `exists` queries if the `_field_names`
field is disabled since it would be a big performance trap.

This commit sets up the default filesystem used during install plugins
tests. A hack is neeeded to handle the temporary directory because the
system property "java.io.tmpdir" will have been initialized to a value
that is sensible for the default filesystem, but not necessarily to a
value that makes sense for the mock filesystem in use during the
tests. This property is restored after each test.
For the refactoring of SortBuilders related to #10217, each SortBuilder needs to get a build()
method that produces a SortField according to the SortBuilder parameters on the shard.
This commit fixes string formatting issues in the error handling and
provides a bettter error message if malformed input is detected.
This commit also adds tests for both situations.
Relates to #17212
this is the last step to remove node level service from IndexShard.
This means that tests can now more easily create an IndexShard instance
without starting a node and removes the dependency between IndexShard and Client/ScriptService
When a master is elected, it reaches out to all master nodes for their cluster state, selecting the one with the highest version. At the moment, we do another round to select the index metadata with the highest version as well. This is not needed - the election of a cluster state is enough - we should just use whatever indices are in it.
Closes#17233
In #17187, we upgrade index state after upgrading
index folder structure. As we don't have to write
the upgraded state in the old index folder structure,
we can cleanup how we write upgraded index state.
We can do better than just throwing an error when we don't find a
setting. It's actually trivial to leverage lucenes slow LD StringDistance
to find possible candiates for a setting to detect missspellings and suggest
a possible setting.
This commit adds error messages like:
* `unknown setting [index.numbe_of_replica] did you mean [index.number_of_replicas]?`
rather than just reporting the setting as unknown
Today if something is wrong with the IndexMetaData we detect it very
late and most of the time if that happens we already allocated the index
and get endless loops and full log files on data-nodes. This change tries
to verify IndexService creattion during initial state recovery on the master
and if the recovery fails the index is imported as `closed` and won't be allocated
at all.
Closes#17187
In 5.0 we don't allow index settings to be specified on the node level ie.
in yaml files or via commandline argument. This can cause problems during
upgrade if this was used extensively. For instance if analyzers where
specified on a node level this might cause the index to be closed when
imported (see #17187). In such a case all indices relying on this
must be updated via `PUT /${index}/_settings`. Yet, this API has slightly
different semantics since it overrides existing settings. To make this less
painful this change adds a `preserve_existing` parameter on that API to ensure
we have the same semantics as if the setting was applied on the node level.
This change also adds a better error message and a change to the migration guide
to ensure upgrades are smooth if index settings are specified on the node level.
If a index setting is detected this change fails the node startup and prints a message
like this:
```
*************************************************************************************
Found index level settings on node level configuration.
Since elasticsearch 5.x index level settings can NOT be set on the nodes
configuration like the elasticsearch.yaml, in system properties or command line
arguments.In order to upgrade all indices the settings must be updated via the
/${index}/_settings API. Unless all settings are dynamic all indices must be closed
in order to apply the upgradeIndices created in the future should use index templates
to set default values.
Please ensure all required values are updated on all indices by executing:
curl -XPUT 'http://localhost:9200/_all/_settings?preserve_existing=true' -d '{

This commit adds a hack to detect when Jimfs throws an IAE where it
should be throwing an UOE. Namely, the method
FileSystemProvider#createDirectory should be throwing an UOE if an
attempt is made to set attributes that the filesystem does not support,
but instead Jimfs violates this and throws an IAE.
There are some implementation of StreamInput that implement the available method
and there are others that do not implement this method. This change makes the
available method abstract in the StreamInput class and implements the method where
it was not previously implemented.
This commit refactors the unit tests for installing plugins to test
against mock filesystems (as well as the native filesystem) for better
test coverage. This commit also adds tests that cover the POSIX
attributes handling when installing plugins (e.g., ensuring that the
plugins directory has the right permissions, the bin directory has
execute permissions, and the config directory has the same owner and
group as its parent).
We current have a ClusterService interface, implemented by InternalClusterService and a couple of test classes. Since the decoupling of the transport service and the cluster service, one can construct a ClusterService fairly easily, so we don't need this extra indirection.
Closes#17183
During the aggregation refactoring the default value for `keyed` in the `percentiles` and `percentile_ranks` aggregation was inadvertently changed from `true` to `false`. This change reverts the defaults to the old (correct) value
Also replaced the PercolatorQueryRegistry with the new PercolatorQueryCache.
The PercolatorFieldMapper stores the rewritten form of each percolator query's xcontext
in a binary doc values field. This make sure that the query rewrite happens only during
indexing (some queries for example fetch shapes, terms in remote indices) and
the speed up the loading of the queries in the percolator query cache.
Because the percolator now works inside the search infrastructure a number of features
(sorting fields, pagination, fetch features) are available out of the box.
The following feature requests are automatically implemented via this refactoring:

Provide better error message when an incompatible node connects to a node
We should give a better exception message when an incompatible node connects
and we receive a messeage. This commit adds a clear excpetion based on the
protocol version received instead of throwing cryptic messages about not fully reaed

The previous method sorted first by _score, then _uid. In certain situations, this allowed
floating point errors to slightly alter the sort order, causing test failure.
We only sort on _uid now, which should be deterministic and allow comparison of ten
documents. Not quite as useful, but less fragile and we still check to make sure num hits
and max score are identical.
Closes#17164
If this query doesn't take the child type into account then it can match other
child document types pointing to the same parent type and that have the same id too.
Today we allow to set all kinds of index level settings on the node level which
is error prone and difficult to get right in a consistent manner.
For instance if some analyzers are setup in a yaml config file some nodes might
not have these analyzers and then index creation fails.
Nevertheless, this change allows some selected settings to be specified on a node level
for instance:
* `index.codec` which is used in a hot/cold node architecture and it's value is really per node or per index
* `index.store.fs.fs_lock` which is also dependent on the filesystem a node uses
All other index level setting must be specified on the index level. For existing clusters the index must be closed
and all settings must be updated via the API on each of the indices.
Closes#16799
This commit fixes an OOM error that happens when the XContentParser.readList() method is asked to parse a single value instead of an array. It fixes the UpdateRequest parsing as well as remove some leniency in the readList() method so that it expect to be in an array before parsing values.
closes#15338
Now we have 16870 we can enable the request cache by default. The caching can still be disabled on a per request basis and can still be disabled in the settings, only the default value has changed. For now this is done regardless of whether the shard is active or inactive.
Closes#17134
This change adds a rewrite phase to the queries on the shard before they are assessed for caching or executed. This allows the opportunity to rewrite queries as faster running simpler queries based on attributes known to only the shard itself. The first query to implement this is the RangeQueryBuilder which will rewrite to a MatchAllQueryBuilder if the range of terms on the shard is a subset of the query and rewrites to a MatchNoneQueryBuilder if the range of terms on the shard is completely outside the query.
Currently, global and index level state format type can be configured through gateway.format.
This commit removes the ability to configure format type for these states.
Now we always store these states in SMILE format and ensure we always write them
to disk in the most compact way.
Adds support for scheduling commands to run at a later time on another
thread pool in the current thread's context:
```java
Runnable someCommand = () -> {System.err.println("Demo");};
someCommand = threadPool.getThreadContext().preserveContext(someCommand);
threadPool.schedule(timeValueMinutes(1), Names.GENERAL, someCommand);
```
This happens automatically for calls to `threadPool.execute` but `schedule`
and `scheduleWithFixedDelay` don't do that, presumably because scheduled
tasks are usually context-less. Rather than preserve the current context
on all scheduled tasks this just makes it possible to preserve it using
the syntax above.
To make this all go it moves the Runnables that wrap the commands from
EsThreadPoolExecutor into ThreadContext.
This, or something like it, is required to support reindex throttling.
For the current refactoring of SortBuilders related to #10217,
each SortBuilder should get a build() method that produces a
SortField according to the SortBuilder parameters on the shard.
This change also slightly refactors the current parse method in
SortParseElement to extract an internal parse method that returns
a list of sort fields only needs a QueryShardContext as input
instead of a full SearchContext. This allows using this internal
parse method for testing.
Without this commit fetching the status of a reindex from a node that isn't
coordinating the reindex will fail. This commit properly registers reindex's
status so this doesn't happen. To do so it moves all task status registration
into NetworkModule and creates a method to register other statuses which the
reindex plugin calls.
When specifying more than one `filter` in a `constant_score`
query, the last one will be the only one that will be
executed, overwriting previous filters. It should rather
raise a ParseException to notify the user that only one
filter query is accepted.
Closes#17126
Fix a potential parsing problem in GeoDistanceSortParser.
For an input like `{ [...], "coerce" = true, "ignore_malformed" = false }` the parser will
fail to parse the ignore_malformed boolean flag and will fall through to the last
else-branch where the boolean flag will be parsed as geo-hash and `ignore_malformed`
treated as field name.
The build currently uses the old maven support in gradle. This commit
switches to use the newer maven-publish plugin. This will allow future
changes, for example, easily publishing to artifactory.
An additional part of this change makes publishing of build-tools part
of the normal publishing, instead of requiring a separate upload step
from within buildSrc. That also sets us up for a follow up to enable
precomit checks on the buildSrc code itself.
This commit removes some dead code that resulted from removing the
ability for a field to have different names (after enforcing that fields
have the same full and index name).
Closes#17127
Test revealed a potential problem in the current GeoDistanceSortParser.
For an input like `{ [...], "coerce" = true, "ignore_malformed" = false }

Adding fix and test that will fail with the old parser code.
Try to renew sync ID if `flush=true` on forceMerge
Today we do a force flush which wipes the sync ID if there is one which
can cause the lost of all benefits of the sync ID ie. fast recovery.
This commit adds a check to renew the sync ID if possible. The flush call
is now also not forced since the IW will show pending changes if the forceMerge added new segments.
if we keep using force we will wipe the sync ID even if no renew was actually needed.

IndicesStore checks for `allocated elsewhere` for every shard not alocated on the local node
On each cluster-state update we check on the local node if we can delete some shards content.
For this we linearly walk all shards and check if they are allocated and started on another node
and if we can delete them locally. if we can delete them locally we go and ask other nodes if we can
delete them and then if the shared IS active elsewhere issue a state update task to delete it. Yet,
there is a bug in IndicesService#canDeleteShardContent which returns `true` even if that shards
datapath doesn't exist on the node which causes tons of unnecessary node to node communication and
as many state update task to be issued. This can have large impact on the cluster state processing
speed.
**NOTE:** This only happens for shards that have at least one shard allocated on the node ie. if an `IndexService` exists.

Add infrastructure to run REST tests on a multi-version cluster
This change adds the infrastructure to run the rest tests on a multi-node
cluster that users 2 different minor versions of elasticsearch. It doesn't implement
any dedicated BWC tests but rather leverages the existing REST tests.
Since we don't have a real version to test against, the tests uses the current version
until the first minor / RC is released to ensure the infrastructure works.
Given the amount of problems this change already found I think it's worth having this run with our test suite by default. The structure of this infra will likely change over time but for now it's a step into the right direction. We will likely want to split it up into integTests and integBwcTests etc. so each plugin can have it's own bwc tests but that's left for future refactoring.
After another round of input from @cbuescher this adds a few more sanity
checks to request parsing.
In addition adds (back) support for the reverse option.
Today index names are often resolved lazily, only when they are really
needed. This can be problematic especially when it gets to mapping updates
etc. when a node sends a mapping update to the master but while the request
is in-flight the index changes for whatever reason we would still apply the update
since we use the name of the index to identify the index in the clusterstate.
The problem is that index names can be reused which happens in practice and sometimes
even in a automated way rendering this problem as realistic.
In this change we resolve the index including it's UUID as early as possible in places
where changes to the clusterstate are possible. For instance mapping updates on a node use a
concrete index rather than it's name and the master will fail the mapping update iff
the index can't be found by it's <name, uuid> tuple.
Closes#17048
Changes:
- no more option to configure eager/lazy loading of the norms (useless now
that orms are disk-based)
- only the `string`, `text` and `keyword` fields support the `norms` setting
- the `norms` setting takes a boolean that decides whether norms should be
stored in the index but old options are still supported to give users time
to upgrade
- setting a `boost` no longer implicitely enables norms (for new indices only,
this is still needed for old indices)
Today, certain bootstrap properties are set and read via system
properties. This action-at-distance way of managing these properties is
rather confusing, and completely unnecessary. But another problem exists
with setting these as system properties. Namely, these system properties
are interpreted as Elasticsearch settings, not all of which are
registered. This leads to Elasticsearch failing to startup if any of
these special properties are set. Instead, these properties should be
kept as local as possible, and passed around as method parameters where
needed. This eliminates the action-at-distance way of handling these
properties, and eliminates the need to register these non-setting
properties. This commit does exactly that.
Additionally, today we use the "-D" command line flag to set the
properties, but this is confusing because "-D" is a special flag to the
JVM for setting system properties. This creates confusion because some
"-D" properties should be passed via arguments to the JVM (so via
ES_JAVA_OPTS), and some should be passed as arguments to
Elasticsearch. This commit changes the "-D" flag for Elasticsearch
settings to "-E".
To make API's output more easy to read we are suppressing stack traces (#12991) unless explicitly requested by setting `error_trace=true` on the request. To compensate we are logging the stacktrace into the logs so people can look it up even the error_trace wasn't enabled. Currently we do so using the `INFO` level which can be verbose if an api is called repeatedly by some automation. For example, if someone tries to read from an index that doesn't exist we will respond with a 404 exception and log under info every time. We should reduce the level to `DEBUG` as we do with other API driven errors. Internal errors (rest codes >=500) are logged as WARN.

When unzipping a plugin zip, the zip entries are resolved relative to
the directory being unzipped into. However, there are currently no
checks that the entry name was not absolute, or relatively points
outside of the plugin dir. This change adds a check for those two cases.
This adds methods and tests to ScriptSortBuilder that
makes it implement NamedWritable and adds the fromXContent
method needed to read itseld from xContent.
Test failures showed problems with passing down
the same collate parameter map reference from the

This changes the collate parameter setters to
make a shallow copy of the map passed in.
This commit adds fields bytes_recovered and files_recovered to the cat

This tries to remove friction to upgrade to 5.0 that would be caused by mapping
changes:
- old ways to specify mapping settings (eg. store: yes instead of store:true)
will still work but a deprecation warning will be logged
- string mappings that only use the most common options will be upgraded
automatically to text/keyword
The change to move dynamic mapping handling to the end of document
parsing has an edge case which can cause dynamic mappings to fail
document parsing. If field a.b is added as an as part of the root update,
followed by a.c.d, then we need to expand the mappers on the stack,
since a is hidden inside the root update which exists on the stack.
This change adds a test for this case, as well as tries to better
document how the logic works for building up the stack before adding a
dynamic mapper.
Sequence of events that lead to the NPE:
- avg metric returns NaN for buckets
- Movavg skips NaN or null buckets, and simply re-uses the existing bucket (e.g. doesn't add

- Derivative references Movavg, the bucket resolution returns null because Movavg wasn't added
to the bucket, NPE when trying to subtract null values
The ingest stats include the following statistics:
* `ingest.total.count`- The total number of document ingested during the lifetime of this node
* `ingest.total.time_in_millis` - The total time spent on ingest preprocessing documents during the lifetime of this node
* `ingest.total.current` - The total number of documents currently being ingested.
* `ingest.total.failed` - The total number ingest preprocessing operations failed during the lifetime of this node
Also these stats are returned on a per pipeline basis.
Currently, the cluster service is tightly coupled to the transport service by both managing node connections and requiring the bound address in order to create the local disco node. This commit introduces a new NodeConnectionsService which is in charge of node connection management and makes it possible to remove all network related calls from the cluster service. The local DiscoNode is now created by DiscoveryNodeService and is set both the cluster service and the transport service during node start up.

Use index UUID to lookup indices on IndicesService
Today we use the index name to lookup index instances on the IndicesService
which applied to search requests but also to index deletion etc. This commit
moves the interface to expect an Index instance which is a tuple
and looks up the index by uuid rather than by name. This prevents accidental modification
of the wrong index if and index is recreated or searching from the wrong index in such a case.
Accessing an index that has the same name but different UUID will now result in an IndexNotFoundException.

This commit adds a guard against an old cluster state that arrives out
of order from the last seen cluster state from the current master from
polluting the pending cluster states queue. Without this guard, such a
state can end up stuck in the pending states queue.
Occasionally the .geohash suffix in Geo{Distance|DistanceRange}Query would conflict with a mapping that defines a sub-field by the same name. This occurs often with nested and multi-fields a mapping defines a geo_point sub-field using the field name "geohash". Since the QueryParser already handles parsing geohash encoded geopoints without requiring the ".geohash" suffix, the suffix parsing can be removed altogether.
This commit removes the .geohash suffix parsing, adds explicit test coverage for the nested query use-case, and adds random distance queries to the nested query test suite.
In particular, this test ensures we don't restart the master node until
we know the index deletion has taken effect on master and the master
eligible nodes.

This was lost in refactoring even on the 2.x branch. The slow-log

for better testabilitly.

_wait_for_completion defaults to false. If set to true then the API will
wait for all the tasks that it finds to stop running before returning. You
can use the timeout parameter to prevent it from waiting forever. If you
don't set a timeout parameter it'll default to 30 seconds.
Also adds a log message to rest tests if any tasks overrun the test. This
is just a log (instead of failing the test) because lots of tasks are run
by the cluster on its own and they shouldn't cause the test to fail. Things
like fetching disk usage from the other nodes, for example.
Switches the request to getter/setter style methods as we're going that

Apparently lucene6 is way more picky with respect to corrupting files
that are not fsynced that's why this test sometimes failed after the lucene6
upgrade.
This commit reduces the maximum number of threads required in the
bootstrap check. This limit can be reduced since the generic thread pool
is no longer unbounded.
Relates #17003
The generic thread pool was previously configured to be able to create
an unlimited number of threads. The thinking is that tasks that are
submitted to its work queue must execute and should not block waiting
for a worker. However, in cases of heavy load, this can lead to an
explosion in the number of threads; this can even lead to a feedback
loop that exacerbates the problem. What is more, this can even bump into
OS limits on the number of threads that can be created.
This commit limits the number of threads in the generic thread pool to
four times the bounded number of processors.

This merge commit merges #16682 which adds the ability to define a index-global

Elasticsearch 5.0 will come with alpha versions which is not supported

Date range aggregations used to be unable to use a `time_zone` parameter to e.g. be applied
int date math roundings like in `now/d` (see #10130 as an example). After the aggregation
refactoring, the time_zone parameter has been pulled up to ValuesSourceAggregatorBuilder
and can now be used in date range aggregations as well.
This change adds randomized time zone settings to the existing IT tests to verify that the
`time_zone` parameter is honored when calculating the bucket boundaries. Also moving
the DateRangeTests from module-groovy/messy back to core as DateRangeIT, sharing
common script mocks with DateHistogramIT and adding documentation for the
`time_zone` parameter in the date range aggregation docs.

update to lucene 6 jars
This commit simplifies and consolidates the two different
implementations of terminals used in tests. There is now a single
MockTerminal which captures output, and allows accessing as one large
string (with unix style \n as newlines), as well as configuring
input.
If the recovery throws an exception we miss to notify the recovery
listener and bubble up the uncaught exception. This commit uses
an AbstractRunnable that also catches rejected execution exceptions
etc. and notifies the listener accordingly.
ClusterModuleTests tests what ShardsAllocatorModuleIT tests without starting
a cluster. Unittests should be preferrred over IT tests anyway and the instantiation
of the balanced shards allocator is tested with every other integration test.
This seems to be an error introduced in refactoring around #16821
where we now wait 30seconds by default if the node already joined
a cluster and got a master. This can slow down tests dramatically
espeically on slow boxes and notebooks.
Closes#16956
No changes were really needed in our test infra as it didn't use `node.client`. Yet it didn't take into account ingest nodes, what we used to call client nodes in InternalTestCluster were actually ingest only nodes, which now become coordinating only nodes.
Also renamed some method to get rid of the node client terminology as much as possible in favour or coordinating only node.
The cluster stats api now returns counts for each node role. The `master_data`, `master_only`, `data_only` and `client` fields have been removed from the response in favour of `master`, `data`, `ingest` and `coordinating_only`. The same node can have multiple roles, hence contribute to multiple roles counts. Every node is implicitly a coordinating node, so whenever a node has no explicit roles, it will be counted as coordinating only.
_cat/nodes used to return `c` for client node or `d` for data node as part of the node.role column. This commit changes it to return `m` for master eligible, `d` for data and/or `i` for ingest. A node with no explicit roles will be a coordinating only node and marked with `-`. A node can obviously have multiple roles. The master column has been adapted to return only whether a node is the current master (`*`) or not (`-`).
A node can now have roles, Role is an enum made of master, data, ingest. A ndoe with no roles is simplicitly a coordinating only node. Roles are resolved once at construction time based on node attributes and never serialized. Moving DiscoveryNode to Writeable helps cleaning up the code, making fields final allow to easily see where roles need to be initialized and do it in one single place.
As discussed in #16565, the node.client setting is an unnecessary shortcut to node.data: false and node.master: false. We have places where we treat nodes with node.client set to true differently compared to master false and data false, which is not correct. Also, with the addition of node.ingest or potentially new roles, it becomes confusing to figure out if a node client should support ingestion or not.
This commit removes the node.client setting in favour being explicit using node.master, node.data and node.ingest instead.
Decommissioning a node or applying a filter inclusion / exclusion can potentially lead to many shards that need to be moved to other nodes. This commit reuses the model across all
shard movements in an allocation round: It calculates the shard model once and simulates the application of all shards that can be moved on this model.
Closes#16926
Today we might run into a rejected execution exception when
we shutdown the node while handling a transport exception. The
exception is run in a seperate thread but that thread might
not be able to execute due to the shutdown. Today we barf and fill
the logs with large exception. This commit catches this exception
and logs it as debug logging instead.
Elasticsearch 5.0 doesn't support indices wiht legacy checksums anymore.
The last time we write legacy checksums was in 1.3.0 which was based
on lucene 4.9 already which means that all files have CRC32 checksums.
All indices that Elasticsearch can read today must be written with
lucene version >= 4.8 anyway so we can drop this layer of backwards
compatibility entirely.
Since we are close to upgrading to Lucene 6.0 we should get rid of this
in a more contiained change than the lucene upgrade.
On shared FS / shadow replicas we rely on a lock retry if the lock has
not yet been relesed on a relocated primary. This commit adds this `hack`
for shared filesystems only.
Closes#16936
The field name is a required argument for all suggesters, but
it was specified via a field() setter in SuggestionBuilder so far.
This changes field name to being a mandatory constructor argument
and lets suggestion builders throw an error if field name is missing
or the empty string.
This commit modifies TransportBulkAction to use relative time instead of
absolute time when measuring how long a bulk request took to be
processed, and adds tests for this functionality.
Closes#16916
`writeLockTimeout` has been removed in Lucene 6 completely and since we have
the shard locking mechanism now for quite a while we don't need this anymore.
Shards should only be allocated once all resources are released such that there
can't be any other shard holding the lock to that index in any sane situation.
This commit removes the ability to use string fields on indices created on or
after 5.0. Dynamic mappings now generate text fields by default for strings
but there are plans to also add a sub keyword field (in a future PR).
Most of the changes in this commit are just about replacing string with
keyword or text. Some tests have been removed because they existed because of
corner cases of string mappings like setting ignore-above on a text field or
enabling term vectors on a keyword field which are now impossible.
The plan is to remove strings entirely in 6.0.
This method was originally introduced to prevent client nodes from connecting to other client nodes directly in the cluster. That said, it worked only if node.client was set to true and not when node.master and node.data were both set to false. It looks safe to remove, which allows to solve all kinds of problems around monitoring that happen wherever there are 2 or more clients nodes in the cluster, and a REST call hits one of them (node counts are off, clients nodes are missing).
Recent simplifications to org.elasticsearch.Version led to "-SNAPSHOT"
to not be displayed in the node version upon startup. Yet, this is
useful information to have. This simple commit adds back the display of
"-SNAPSHOT" in the version on startup if the build is a snapshot build.
Closes#16908
This commit refactors the bootstrap checks into a dedicated class. The
refactoring provides a model for different limits per operating system,
and provides a model for unit tests for individual checks.
Closes#16844
This is a backport of #16845 in this branch.
We now also support marking settings with `SettingsProperty.Deprecated`.
If the setting is still used, it will print a `warn` to the user.
In this case we compute elapsed time and `System.nanoTime()` is designed to do just do that.
The absolute timing `System.currentTimeMillis()` provides in not needed and the relative timing `System.nanoTime()` provides is likely to be more accurate.
Use 'includeSegmentFileSizes' as the flag name to report disk usage.
Added test that verifies reported segment disk usage is growing accordingly after adding a document.
Documentation: Reference the new parameter as part of indices stats.
In 2.2, the client nodes created internally by a tribe node were changed
to be explicit about which settings the client nodes use, no longer
loading all settings from elasticsearch.yml. However, some settings were
missed, notably network bind settings. This change adds those settings
to be passed through, as well as adds unit tests for building the tribe
client node settings.
I've noticed throughout the code that we have a need to remove the boilerplate lifecycle check when starting/rescheduling certain runnables. This provides a simpler implementation to get this functionality without duplicating it.
The `ingest_took` is separate from `took`, which keeps track how much time is spent on indexing/deleting/updating.
The `ingest_took` is only visible in the rest response if at least for one bulk item has ingest enabled.
Currently each suggestion keeps track of its own name. This has
the disadvantage of having to pass down the parsed name property
in the suggestions fromXContent() and the serialization methods
as an argument, since we need it in the ctor.
This change moves the naming of the suggestions to the surrounding
SuggestBuilder and by this eliminates the need for passind down
the names in the parsing and serialization methods. By making
`name` a required argument in SuggestBuilder#addSuggestion() we
also make sure it is always set and prevent using the same name twice,
which wasn't possible before.
In case where the publish address is different to all bound addresses and an explicit publish_port
setting is not provided, the publish_port is now selected as the unique port of bound addresses.
An exception is thrown in case of ambiguities.
Closes#16626
If a node was isolated from the cluster while a delete was happening,
the node will ignore the deleted operation when rejoining as we couldn't
detect whether the new master genuinely deleted the indices or it is a
new fresh "reset" master that was started without the old data folder.
We can now be smarter and detect these reset masters and actually delete
the indices on the node if its not the case of a reset master.
Note that this new protection doesn't hold if the node was shut down. In
that case it's indices will still be imported as dangling indices.
Closes#16825Closes#11665
If you connect to a client node and call _cat/nodes, and there is at least another client node in the cluster, the http address cannot be retrieved thus we get an NPE. This commit prevents an NPE from being thrown. This bug was introduced with #16770
The suffix TransportAction is misleading as it may make think that it extends TransportAction, but it does not. This class makes accessible the different search operations exposed by SearchService through the transport layer. Also resolved few compiler warnings in the class itself.
The big win here is catching tests that are incorrectly named and will
be skipped by gradle, providing a false sense of security.
The whole thing takes about 10 seconds on my Macbook Air, not counting
compiling the test classes, which seems worth it. Because this runs as
a gradle task with propery UP-TO-DATE handling it can be skipped if the
tests haven't been changed which should save some time.
I chose to keep this in test:framework rather than a new subproject of
buildSrc because ESIntegTestCase and doesn't inroduce any additional
dependencies.
DiscoveryService was a bridge into the discovery universe. This is unneeded and we can just access discovery directly or do things in a different way.
One of those different ways, is not having a dedicated discovery implementation for each our dicovery plugins but rather reuse ZenDiscovery.
UnicastHostProviders are now classified by discovery type, removing unneeded checks on plugins.
Closes#16821
Its useful when you need to have defaults that don't match
SearchSourceBuilder's defaults. You build your SearchSourceBuilder, set the
defaults, and then layer the XContent on top of that.
TransportSearchTypeAction and subclasses are not actually transport actions, but just support classes useful for their inner async actions that can easily be extracted out so that we get rid of one too many level of abstraction.
Same pattern can be applied to TransportSearchScrollQueryAndFetchAction & TransportSearchScrollQueryThenFetchAction which we could remove in favour of keeping only their inner classes named SearchScrollQueryAndFetchAsyncAction and SearchScrollQueryThenFetchAsyncAction.
Remove org.elasticsearch.action.search.type package, collapsed remaining classes into existing org.elasticsearch.action.search package
Make also ParsedScrollId ScrollIdForNode and TransportSearchHelper classes and their methods package private.
Closes#11710
As we rely on active allocation ids persisted in the cluster state to select
the primary shard copy, we can write shard state metadata on the allocated node
as soon as the node knows about receiving this shard. This also ensures that
in case of primary relocation, when the relocation target is marked as started
by the master node, the shard state metadata with the correct allocation id has
already been written on the relocation target. Before this change, shard state
metadata was only written once the node knows it is marked as started. In case
of failures between master marking the node as started and the node
receiving and processing this event, the relation between the shard copy on disk
and the cluster state could get lost. This means that manual allocation of
the shard using the reroute command allocate_stale_primary was necessary.
Closes#16625
Instead of modifying methods each time we need to add a new behavior for settings, we can simply pass `SettingsProperty... properties` instead.
`SettingsProperty` could be defined then:
```
public enum SettingsProperty {
Filtered,
Dynamic,
ClusterScope,
NodeScope,
IndexScope
// HereGoesYours;
}
```
Then in setting code, it become much more flexible.
TODO: Note that we need to validate SettingsProperty which are added to a Setting as some of them might be mutually exclusive.
As part of #10136 we removed the transport action for broadcast deletes in case routing is required but not specified. Bulk api worked differently though and kept on doing the broadcast delete internally in that case. This commit makes sure that delete items are marked as failed in such cases. Also the check has been moved up in the code together with the existing check for the update api, and we now make sure that the exception is the same as the one thrown for single document apis (delete/update).
Note that the failure for the update api contained the wrong optype (the type of the document rather than "update"), that's been fixed too and tested.
Closes#16645
This commit disables the production limits checks on snapshot
builds. This is at a minimum short-term relief for developers that do in
fact bind to external network interfaces, and is possibly a long-term
fix as well. The situation with using the JVM flag MaxFDLimit is far too
complicated.
Closes#16835
At some time in the distant past, Bootstrap could be used by those
embedding elasticsearch. However, it is no longer allowed (now package
private), and so any errors (for example, log4j missing, or any other
exception while initializing) should be exposed directly and cause
elasticsearch to fail to start. This change removes hiding of logging
initialization exceptions.
Removes all our logger wrappers except the wrapper for log4j1.2. If you
depend on Elasticsearch's jar in your application you'll need to declare
log4j 1.2 and/or some bridge to your favorite logger.
We did this to simplify our builds and code. No more commons-logging like
log implementation sniffing. No more optional dependency hacks in gradle.
We might one day want to use j.u.l instead of log4j. If we do want that
we can recover its wrapper by studying this commit. We didn't go directly
to j.u.l in this commit because that is a bigger change. Our logging
configuration is based on log4j1.2 and people are used to it. So it'd
be a much more fraught breaking change to do that conversion.
It is possible to register multiple settings with complex matchers that could both match
a given key. The behavior when this occurs can lead to issues and depends on the
number of settings that have been registered. In order to identify the setting for a given
key, we iterate over the values in a map to find the first setting that matches the given key
and iteration order of a map should not be relied upon.
This commit checks complex settings when adding them and if the keys for these overlap,
an IllegalArgumentException is now thrown.
Currently dynamic mappings propgate through call semantics, where deeper
dynamic mappings are merged into higher level mappings through
return values of recursive method calls. This makese it tricky
to handle multiple updates in the same method, for example when
trying to create parent object mappers dynamically for a field name
that contains dots.
This change makes the api for adding mappers a simple list
of new mappers, and moves construction of the root level mapping
update to the end of doc parsing.
We should open up the node to the world when it's as ready as possiblAt the moment we open up the transport service before the local node has been fully initialized. This causes bug as some data structures are not fully initialized yet. See for example #16723.
Sadly, we can't just start the TransportService last (as we do with the HTTP server) because the ClusterService needs to know the bound published network address for the local DiscoveryNode. This address can only be determined by actually binding (people may use, for example, port 0). Instead we start the TransportService as late as possible but block any incoming requests until the node has completed initialization.
A couple of other cleanup during start time:
1) The gateway service now starts before the initial cluster join so we can simplify the logic to recover state if the local node has become master.
2) The discovery is started before the transport service accepts requests, but we only start the join process later using a dedicated method.

This commit removes the system property "es.useLinkedTransferQueue" that
defaulted to false and was used to control the queue implementation used
in a few places.
Closes#16786
This commit adds a check on startup for G1 GC while running on early
versions of HotSpot version 25. This is to prevent potential data
corruption issues that can occur on those versions.
Closes#16737
Java NIO has the notion of gathering writes. These are writes that
gather data from multiple buffers into a single channel. These gathering
writes in Netty have been enabled by default with the possibility to
disable them using "es.netty.gathering". This flag was added in case
having gathering writes on by default did not work out. We have not
published this ability and sufficient time has passed to render
judgement that using gathering writes is okay.
Closes#16774
Expose http address in cat/nodes and cat/nodeattrs APIs
We expose a lot of information like IP address and port but never
expose the http address/ip:port in the CAT API. It's nice to have it
there too since otherwise json parsing is required to get this information

Elasticsearch should reject ids that are this long, to ensure a document
always remains retrievable for clients that impose a maximum URI length

Most elements in SearchSourceBuilder (e.g. aggs, queries) write their top-level
ParseField name in toXContent(), while HighlightBuilder used to do it in
its own toXContent() method. Moved this up so SeachSourceBuilder for consistency.
Today we might start a node and some of the paths might not have the
required permissions. This commit goes through all data directories as
well as index, shard and state directories and ensures we have write access.
To make this work across all OS etc. we are trying to write a real file
and remove it again in each of those directories
This commit removes the es.max-open-files flag as the same information
can be obtained from the cluster nodes info API, and is warn logged on
startup if it's set too low anyway.
Closes#16757
This commit tries to 'guess' if a user starts a node in production by
checking if any network host is configured. If that is the case soft-limits
that are only logged otherwise are enforced like number of open file descriptors.
Closes#16727
Today we have the notion of a snapshot inside Version.java which makes
releasing complicated since to do a release Version.java must be changed.
This commit removes all notions of snapshot from the code and allows to
switch between snapshot and release build by specifying a system property on
the build. For instance running:
```
gradle run -Dbuild.snapshot=false
```
will build and package a release build while the default always
builds snapshots. Calls to the main rest action will still get the snapshot
information rendered out with the response.
This was changed when adding the text field in an attempt to clean up
how analyzers are set. Unfortunately this change was not safe for the
string field given that it can also represent keywords.
Also renamed histogram.AbstractBuilcer to AbstractHistogramBuilder, range.AbstractBuilder to AbstractRangeBuilder and org.elasticsearch.search.aggregations.pipeline.having to org.elasticsearch.search.aggregations.pipeline.bucketselector
Function Score Query now checks the type of token that we are parsing, which makes parsing stricter and allows to throw useful errors in case the json is malformed. It also makes code more readable as in what gets parsed when.

This commit updates the OrdinalsBuilder and GeoPoint FieldData loader to work with the new PREFIX_ENCODING introduced in lucene-5.5.0. Backcompat is included to support legacy encoding types.
closes#16634
After #15776 got in, we don't need these copy constructors anymore. When we used to copy requests it was to make sure that headers and context were copied from the parent requests (e.g. index/delete as part of update). This is not a problem anymore.
Now we have a nice Setting infra, we can define in Setting class if a setting should be filtered or not.
So when we register a setting, setting filtering would be automatically done.
Instead of writing:
```java
Setting<String> KEY_SETTING = Setting.simpleString("cloud.aws.access_key", false, Setting.Scope.CLUSTER);
settingsModule.registerSetting(AwsEc2Service.KEY_SETTING, false);
settingsModule.registerSettingsFilterIfMissing(AwsEc2Service.KEY_SETTING.getKey());
```
We could simply write:
```java
Setting<String> KEY_SETTING = Setting.simpleString("cloud.aws.access_key", false, Setting.Scope.CLUSTER, true);
settingsModule.registerSettingsFilterIfMissing(AwsEc2Service.KEY_SETTING.getKey());
```
It also removes `settingsModule.registerSettingsFilterIfMissing` method.
The plan would be to remove as well `settingsModule.registerSettingsFilter` method but it still used with wildcards. For example in Azure Repository plugin:
```java
module.registerSettingsFilter(AzureStorageService.Storage.PREFIX + "*.account");
module.registerSettingsFilter(AzureStorageService.Storage.PREFIX + "*.key");
```
Closes#16598.
The current logic for doing recovery from a source to a target shourd is tightly coupled with the underlying network pipes. This changes decouple the two, making it easier to add unit tests for shard recovery that doesn't involve the node and network environment.
On top that, RecoveryTarget is renamed to RecoveryTargetService leaving space to renaming RecoveryStatus to RecoveryTarget (and thus avoid the confusion we have today with RecoveryState).
Correspondingly RecoverySource is renamed to RecoverySourceService.
Closes#16605
All we do is check the cancelled flag and stop the request at a few key
points.
Adds the cancellation cause to the status so any request that is cancelled
but doesn't die can be seen in the task list.
The `keyword` field is intended to replace `not_analyzed` string fields. It is
indexed and has doc values by default, and doesn't support enabling term
vectors.
Although it doesn't support setting an analyzer for now, there are plans for
it to support basic normalization in the future such as case folding.
2.x has show so far that running with security manager is the way to go.
This commit make this non-optional. Users that need to pass their own rules
can still do this via the system configuration for the security manager. They
can even opt out of all security that way.
This commit moves IndicesRequestCache into o.e.indics and makes all API in this
class package private. All references to SearchReqeust, SearchContext etc. have been factored
out and relevant glue code has been added to IndicesService. The IndicesRequestCache is not a
simple class without any hard dependencies on ThreadPool nor SearchService or IndexShard. This now
allows to add unittests.
This commit also removes two settings `indices.requests.cache.clean_interval` and `indices.fielddata.cache.clean_interval`
in favor of `indices.cache.clean_interval` which cleans both caches.
Some bw incompatible setting changes:
http.netty.http.blocking_server -> http.tcp.blocking_server
http.netty.host (removed, we just have http.host)
http.netty.bind_host (removed, we just have http.bind_host)
http.netty.publish_host (removed, we just have http.publish_host)
http.netty.tcp_no_delay -> http.tcp.no_delay
http.netty.tcp_keep_alive -> http.tcp.keep_alive
http.netty.reuse_address -> http.txp.reuse_address
http.netty.tcp_send_buffer_size -> http.tcp.send_buffer_size
http.netty.tcp_receive_buffer_size -> http.tcp.receive_buffer_size
Closes#16531
this is a minor cleanup that detaches `IndicesRequestCache` and `IndicesQueryCache`
from guice and moves it into `IndicesService`. It also decouples the `IndexShard` and `IndexService`
from these caches which are unnecessary dependencies.
QueryBuilders today do all their heavy lifting in toQuery() which
can be too late for several operations. For instance if we want to fetch geo shapes
on the coordinating node we need to do all this before we create the actual lucene query
which happens on the shard itself. Also optimizations for request caching need to be done
to the query builder rather than the query which then in-turn needs to be serialized again.
This commit adds the basic infrastructure for query rewriting and moves the heavy lifting into
the rewrite method for the following queries:
* `WrapperQueryBuilder`
* `GeoShapeQueryBuilder`
* `TermsQueryBuilder`
* `TemplateQueryBuilder`
Other queries like `MoreLikeThisQueryBuilder` still need to be fixed / converted. The nice
sideeffect of this is that queries like template queries will now also match the request cache
if their non-template equivalent has been cached befoore. In the future this will allow to
add optimizataion like rewriting time-based queries into primitives like `match_all_docs` or `match_no_docs`
based on the currents shards bounds. This is especially appealing for indices that are read-only ie. never change.
In the testCanFetchIndexStatus the task check can occur before the indexing process is started making the test to fail. This commit adds an additional lock to make sure we check tasks only after at least one of the tasks is registered.
This adds a build method for the SuggestionContext to the PhraseSuggestionBuilder
and another one that creates the SuggestionSearchContext to the top level
SuggestBuilder. Also adding tests that make sure the current way of parsing
xContent to a SuggestionContext is reflected in the output the builders create.
This commit removes bootstrap support for Java Service Wrapper. The
implementation of this has been moved to its own repository where it was
deprecated, does not work with Elasticsearch 2.x, and is untested and
therefore unmaintained.
Closes#16580
This commit handles the scenario where a replication action fails on a
replica shard, the primary shard attempts to fail the replica shard
but the primary shard is notified of demotion by the master. In this
scenario, the demoted primary shard must be failed, and then the
request rerouted again to the new primary shard.
Closes#16415, closes#14252
Adds to GeoDistanceSortBuilder:
* equals
* hashcode
* writeto/readfrom
* moves xcontent parsing logic over
* adds roundtrip tests
* fixes roundtrip test for xcontent by keeping points just as geopoints not geohashes internally
* fixes xcontent parsing of ignore_malformed if coerce is set/unset
* adds exception to sortMode setter to avoid setting invalid sort modes
Relates to #15178
Today put mapping operations only update metadata of the type that is being
modified, which is not enough since some modifications may have side-effects
on other types.
Closes#16239
Only tasks that extend CancellableTask can be cancelled using this mechanism. If a cancellable task has children it can elect to cancel all child tasks as well. In this case a special ban parent request is sent to all nodes. This request does two things: 1) it prevents any tasks with the banned parent task from being started, and 2) it cancels all currently running tasks that have the banned task as a parent. The ban is lifted as soon as the coordinating node notifies all other nodes that the cancelled task has finished executing. If the coordinating node leaves the cluster before it has a chance to lift its bans, all bans set by this coordinating node are automatically removed.
As an option a task can elect to automatically cancel all child tasks if their parent task was running on a node that just left the cluster. This option makes sense for cancellable heavy tasks that have no side-effects and only return results to the coordinating node. With the coordinating node gone, it doesn't make sense to run such tasks any longer since their results will be most likely discarded.
