Make TranslogConfig immutable and pass TranslogGeneration as a ctor arg to Translog
[reindex] Don't get rejected
Remove redundant commit - #openTranslog() already commits in that case
...
The introduction of max number of processes and max size virtual memory
checks inadvertently made JNA non-optional on OS X and Linux. This
commit wraps these calls in a check to see if JNA is available so that
JNA remains optional.
Closes#17492
Make TranslogConfig immutable and pass TranslogGeneration as a ctor arg to Translog
This mutable state is confusing and is easily missed. By default this is null and
wipes all translog. This commit makes the TranslogGeneration mandatory on the Translog
constructor and removes the mutalbe state.
We already protect against making decisions based on an inflight cluster state if someone asks for a waitFor rule (like wait for green). We should do the same for normal health checks as well (unless timeout is set to 0) as it be trappy to debug failures when health says the cluster is in a certain state, but that state wasn't applied yet.
Closes#17440
FieldStatsProvider had to perform instanceof calls to properly handle dates or
ip addresses. By moving the logic to MappedFieldType, each field type can check
whether all values are within bounds its way.
Note that this commit only keeps rewriting support for dates, which are the only
field for which the rewriting mechanism is likely to help (because of time-based
indices).
This mutable state is confusing and is easily missed. By default this is null and
wipes all translog. This commit makes the TranslogGeneration mandatory on the Translog
constructor and removes the mutalbe state.
Move translog recover outside of the engine
We changed the way we manage engine memory buffers to an
open model where each shard can essentially has infinite memory.
The indexing memory controller is responsible for moving memory to disk
when it's needed. Yet, this doesn't work today when we recover from store/translog
since the engine is not fully initialized such that IMC has no access to the engine,
neither to it's memory buffer nor can it move data to disk.
The biggest issue here is that translog recovery happends inside the Engine constructor
which is problematic by itself since it might take minutes and uses a not yet fully
initialzied engine to perform write operations on.
This change detaches the translog recovery and makes it the responsibility of the caller
to run it once the engine is fully constructed or skip it if not necessary.
Changes QueryParser into a @FunctionalInterface and provides a way to
register queries using that. Cuts match and function_score queries over
to that registration method as a proof of concept.
Once all queries have been cut over we can remove their PROTOTYPES.
Currently our testing of parsing query builders is limited to the
default order of the parameters that each builders toXContent()
method produces. To better test real queries where the order of
parameters can be different, this change adds a helper
method to ESTestCase that takes a XContentBuilder and randomly
shuffles the order of the fields inside an object. This is
used in AbstractQueryTestCase, but it can be used in other similar
places in the future.
The refactoring of RescoreBuilder and QueryRescoreBuilder moved parsing
previously in RescoreParseElement into the builders. This removes the
left over parse element.
By default, tasks are grouped by node. However, task execution in elasticsearch can be quite complex and an individual task that runs on a coordinating node can have many subtasks running on other nodes in the cluster. This commit makes it possible to list task grouped by common parents instead of by node. When this option is enabled all subtask are grouped under the coordinating node task that started all subtasks in the group. To group tasks by common parents, use the following syntax:
GET /tasks?group_by=parents

This allows the user to update the reindex throttle on the fly, with changes
that speed up the throttling being applied immediately and changes that
slow down the throttling being applied during the next batch. This means
that if a user throttles reindex in such a way that it tries to sleep for
16 years and then realizes that they've done something wrong then they
can change the throttle and reindex will wake up again. We don't apply
slow downs immediately so we never get in danger of losing the scan context.
Also, if reindex is canceled while it is sleeping (how it honor throttling)
then it'll immediately wake up and cancel itself.
The old HighlightParseElement was only left because it was still
used in tests and some places in InnerHits. This PR removes it
and replaces the tests that checked that the original parse element
and the rafactored highlighter code produce the same output with
new tests that compare builder input to the SearchContextHighlight
that is created.
This commit adds the new `action.search.shard_count.limit` setting which
configures the maximum number of shards that can be queried in a single search
request. It has a default value of 1000.
Today we don't invoke `IndexingOperationListeners` when we are running
a recovery form store or replaying translog from remote. This is problematic since
the actual code path for indexing is different between normal indexing and recovery.
An important detail is left out on recovery since we implemented the `IndexingMemoryController`
as an `IndexingOperationListener` we might never flush the `IndexWriter` of a recovering shard
which can lead to `OOMs` on node startup / recovery.
Both top level and inline inner hits are now covered by InnerHitBuilder.
Although there are differences between top level and inline inner hits,
they now make use of the same builder logic.
The parsing of top level inner hits slightly changed to be more readable.
Before the nested path or parent/child type had to be specified as encapsuting
json object, now these settings are simple fields. Before this was required
to allow streaming parsing of inner hits without missing contextual information.
Once some issues are fixed with inline inner hits (around multi level hierachy of inner hits),
top level inner hits will be deprecated and removed in the next major version.
This commit introduces SearchOperationListeneres which allow to hook
into search operation lifecycle and execute operations like slow-logs
and statistic collection in a transparent way. SearchOperationListenrs
can be registered on the IndexModule just like IndexingOperationListeners.
The main consumers (slow log) have already been moved out of IndexService
into IndexModule which reduces the dependency on IndexService as well as
IndexShard and makes slowlogging transparent.
Closes#17398
`text` fields will have fielddata disabled by default. Fielddata can still be
enabled on an existing index by setting `fielddata=true` in the mappings.
Remove ability to specify arbitrary node attributes with `node.` prefix
Today the basic node settings like `node.data` and `node.master` can't really be fully validated
since we allow to specify custom user attributes on the node level. We have to, in order to
support that, add a wildcard setting for `node.*` to let these setting pass validation.
Instead we should require a more contraint prefix like `node.attr.` that defines a namespace
that is reserved for user attributes.
This commit adds a new namespace for attributes in `node.attr`.

Merges #17340
With restriction for the total number of fields introduced in #17357 this test can fail if a large number of records is randomly selected for indexing.
This is to prevent mapping explosion when dynamic keys such as UUID are used as field names. index.mapping.total_fields.limit specifies the total number of fields an index can have. An exception will be thrown when the limit is reached. The default limit is 1000. Value 0 means no limit. This setting is runtime adjustable
Closes#11443
Transport client was replacing the address of the nodes connecting to with the ones received from the liveness api rather keeping the original listed nodes. Written a test for that.

Add API to explain why a shard is or isn't assigned
...
In extreme cases a local primary shard can be replaced with a replica while a replication request is in flight and the primary action is applied to the shard (via `acquirePrimaryOperationLock()). #17044 changed the exception used in that method to something that isn't recognized as `TransportActions.isShardNotAvailableException`, causing the operation to fail immediately instead of retrying. This commit fixes this by check the primary flag before
acquiring the lock. This is safe to do as an IndexShard will never be demoted once a primary.
Closes#17358
If a terms aggregation was ordered by a metric nested in a single bucket aggregator which did not collect any documents (e.g. a filters aggregation which did not match in that term bucket) an ArrayOutOfBoundsException would be thrown when the ordering code tried to retrieve the value for the metric. This fix fixes all numeric metric aggregators so they return their default value when a bucket ordinal is requested which was not collected.
Closes#17225
For geo distance sort parsing: Disallow anything but
VALUE_STRING as geo hash, disallow resetting field
name for geo fields.
Also make error message for wrong lat/lon values more
verbose by including the affected field name.
If you add a string field to a document, it will have the following default
mapping:
```
{
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
```
Today, if you call /index/type/_search instead of /index/_search, elasticsearch
will automatically insert a type filter to only match documents of the given
type. This commit uses a new TypeQuery instead of a TermQuery for this filter,
which rewrites to a MatchAllDocsQuery when all documents of a shard match the
filtered type. This is helpful because BooleanQuery has a special rewrite rule
to remove MatchAllDocsQuery as FILTER clauses. So for instance if your query is
`+body:"quick fox" #_type:my_type`, it will be rewritten to
`+body:"quick fox" #*:*` which is then rewritten to `body:"quick fox"`.
This adds a new `/_cluster/allocation/explain` API that explains why a
shard can or cannot be allocated to nodes in the cluster. Additionally,
it will show where the master *desires* to put the shard, according to
the `ShardsAllocator`.
It looks like this:
```
GET /_cluster/allocation/explain?pretty
{
"index": "only-foo",
"shard": 0,
"primary": false
}
```
Though, you can optionally send an empty body, which means "explain the
allocation for the first unassigned shard you find".
The output when a shard is unassigned looks like this:
```
{
"shard" : {
"index" : "only-foo",
"index_uuid" : "KnW0-zELRs6PK84l0r38ZA",
"id" : 0,
"primary" : false
},
"assigned" : false,
"unassigned_info" : {
"reason" : "INDEX_CREATED",
"at" : "2016-03-22T20:04:23.620Z"
},
"nodes" : {
"V-Spi0AyRZ6ZvKbaI3691w" : {
"node_name" : "Susan Storm",
"node_attributes" : {
"bar" : "baz"
},
"final_decision" : "NO",
"weight" : 0.06666675,
"decisions" : [ {
"decider" : "filter",
"decision" : "NO",
"explanation" : "node does not match index include filters [foo:\"bar\"]"
} ]
},
"Qc6VL8c5RWaw1qXZ0Rg57g" : {
"node_name" : "Slipstream",
"node_attributes" : {
"bar" : "baz",
"foo" : "bar"
},
"final_decision" : "NO",
"weight" : -1.3833332,
"decisions" : [ {
"decider" : "same_shard",
"decision" : "NO",
"explanation" : "the shard cannot be allocated on the same node id [Qc6VL8c5RWaw1qXZ0Rg57g] on which it already exists"
} ]
},

And when the shard *is* assigned, the output looks like:
```
{
"shard" : {
"index" : "only-foo",
"index_uuid" : "KnW0-zELRs6PK84l0r38ZA",
"id" : 0,

},
"Qc6VL8c5RWaw1qXZ0Rg57g" : {
"node_name" : "Slipstream",
"node_attributes" : {
"bar" : "baz",
"foo" : "bar"
},
"final_decision" : "CURRENTLY_ASSIGNED",
"weight" : 0.0,
"decisions" : [ {
"decider" : "same_shard",
"decision" : "NO",
"explanation" : "the shard cannot be allocated on the same node id [Qc6VL8c5RWaw1qXZ0Rg57g] on which it already exists"
} ]
},
"PzdyMZGXQdGhqTJHF_hGgA" : {
"node_name" : "The Symbiote",
"node_attributes" : { },
"final_decision" : "NO",
"weight" : 3.6999998,
"decisions" : [ {
"decider" : "filter",
"decision" : "NO",
"explanation" : "node does not match index include filters [foo:\"bar\"]"
} ]
}
}
}
```
Only "NO" decisions are returned by default, but all decisions can be
shown by specifying the `?include_yes_decisions=true` parameter in the
request.

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.

This commit fixes a bug that was causing the result of TransportTasksAction#filterNodeIds to be ignored and as a result the tasks actions were executed on all nodes.
Node roles are now serialized as well, they are not part of the node attributes anymore. DiscoveryNodeService takes care of dividing settings into attributes and roles. DiscoveryNode always requires to pass in attributes and roles separately.
discovery.zen.minimum_master_nodes is the single most important setting to set on a production cluster. We have no way of supplying a good default so it must be set by the user. Binding a node to a public IP (as opposed to the default local host) is a good enough indication that a node will be part of a production cluster cluster and thus it's a good tradeoff to enforce the settings. Note that nothing prevent users from setting it to 1 in a single node cluster.
Closes#17288
Primary terms is a way to make sure that operations replicated from stale primary are rejected by shards following a newly elected primary.
Original PRs adding this to the seq# feature branch #14062 , #14651 . Unlike those PR, here we take a different approach (based on newer code in master) where the primary terms are stored in the meta data only (and not in `ShardRouting` objects).
Relates to #17038Closes#17044
If a Writeable.Reader returns null it is always a bug, probably one that
will cause corruption in the StreamInput it was trying to read from. This
commit adds a check that attempts to catch these errors quickly including
the name of the reader.
We currently have a `discovery.zen.master_election.filter_client` setting that control whether their ping responses are ignored for master election (which is the current default). With the push to treat client nodes as normal nodes (and promote the transport/rest clients for client work), this should be changed. This commit remove this setting and it's companion `discovery.zen.master_election.filter_data` setting (currently defaulting to false) in favor of singe `discovery.zen.master_election.ignore_non_master_pings` setting with more intuitive name (defaulting to false).
Resolves#17325Closes#17329
readFrom is confusing because it requires an instance of the type that it
is reading but it doesn't modify it. But we also have (deprecated) methods
named readFrom that *do* modify the instance. The "right" way to implement
the non-modifying readFrom is to delegate to a constructor that takes a
StreamInput so that the read object can be immutable. Now that we have
`@FunctionalInterface`s it is fairly easy to register things by referring
directly to the constructor.
This change modifying NamedWriteableRegistry so that it does that. It keeps
supporting `registerPrototype` which registers objects to be read by
readFrom but deprecates it and delegates it to a new `register` method
that allows passing a simple functional interface. It also cuts Task.Status
subclasses over to using that method.
The start of #17085
The available memory metric was always set to `0` since 2.0.beta1 (bug). was left behind but never set. Turns out the section wasn't that useful, as it would only output the total memory available throughout all nodes in the cluster. We decided to remove the section then.

This commit fixes a line-length checkstyle violation in
PropertiesSettingsLoader.java and removes this file from the checkstyle
line-length suppressions.
The sole constructor of XContentSettingsLoader accepts a boolean flag
that indicates whether or not null values parsed from the source should
be rejected or not. Previously a true value for this flag meant that
null values should be rejected. With this commit, the meaning of this
flag is reversed so that a true value means that null values should be
accepted (note that this is needed due to the way that settings are
unset via the cluster update settings API). The name of this flag has
been changed from guardAgainstNullValuedSettings to allowNullValues, for
clarity.
All our fields are supposed to support multi fields, so we could put the logic in
`TypeParsers.parseField` instead of duplicating the logic in every type parser.

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.
