Today when parsing a request, Elasticsearch silently ignores incorrect
(including parameters with typos) or unused parameters. This is bad as
it leads to requests having unintended behavior (e.g., if a user hits
the _analyze API and misspell the "tokenizer" then Elasticsearch will
just use the standard analyzer, completely against intentions).
This commit removes lenient URL parameter parsing. The strategy is
simple: when a request is handled and a parameter is touched, we mark it
as such. Before the request is actually executed, we check to ensure
that all parameters have been consumed. If there are remaining
parameters yet to be consumed, we fail the request with a list of the
unconsumed parameters. An exception has to be made for parameters that
format the response (as opposed to controlling the request); for this
case, handlers are able to provide a list of parameters that should be
excluded from tripping the unconsumed parameters check because those
parameters will be used in formatting the response.
Additionally, some inconsistencies between the parameters in the code
and in the docs are corrected.

This commit changes the default behavior of `_flush` to block if other flushes are ongoing.
This also removes the use of `FlushNotAllowedException` and instead simply return immediately
by skipping the flush. Users should be aware if they set this option that the flush might or might
not flush everything to disk ie. no transactional behavior of some sort.

We can now run templates using `explain` and/or `profile` parameters.
Which is interesting when you have defined a complicated profile but want to debug it in an easier way than running the full query again.
You can use `explain` parameter when running a template:
```js
GET /_search/template
{
"file": "my_template",
"params": {
"status": [ "pending", "published" ]
},
"explain": true
}
```
You can use `profile` parameter when running a template:
```js
GET /_search/template
{
"file": "my_template",
"params": {
"status": [ "pending", "published" ]
},
"profile": true
}
```
The command-line arguments for Elasticsearch must now be specified using
-E. This commit fixes the usage of command-line arguments in the REST
API spec README.
The only repository we can be sure is safe to clean is `fs` so we clean
any snapshots in those repositories after each test. Other repositories
like url and azure tend to throw exceptions rather than let us fetch
their contents during the REST test. So we clean what we can....
Closes#18159
The refresh description should indicate that the affected shards are
refreshed as opposed to the entire index.
This was raised as a discrepancy on
discuss (https://discuss.elastic.co/t/refresh-parameter-of-index-api/59008/2)
on the .NET client that originates from code generated from the rest api
spec. The description has been updated in master but should be updated
for the 2.4.0 release.
We put the rest api spec into a jar for upload to maven, so that we can
use within external rest tests. This change adds making a pom for maven
(as well as producing sources and javadoc jars, even though they will be
empty, because maven central requires them).
This change replaces the fields parameter with stored_fields when it makes sense.
This is dictated by the renaming we made in #18943 for the search API.
The following list of endpoint has been changed to use `stored_fields` instead of `fields`:
* get
* mget
* explain
The documentation and the rest API spec has been updated to cope with the changes for the following APIs:
* delete_by_query
* get
* mget
* explain
The `fields` parameter has been deprecated for the following APIs (it is replaced by _source filtering):
* update: the fields are extracted from the _source directly.
* bulk: the fields parameter is used but fields are extracted from the source directly so it is allowed to have non-stored fields.
Some APIs still have the `fields` parameter for various reasons:
* cat.fielddata: the fields paramaters relates to the fielddata fields that should be printed.
* indices.clear_cache: used to indicate which fielddata fields should be cleared.
* indices.get_field_mapping: used to filter fields in the mapping.
* indices.stats: get stats on fields (stored or not stored).
* termvectors: fields are retrieved from the stored fields if possible and extracted from the _source otherwise.
* mtermvectors:
* nodes.stats: the fields parameter is used to concatenate completion_fields and fielddata_fields so it's not related to stored_fields at all.

returned could be 0%. The yaml tests check that the free/used

Currently it does not because our parsers do not support big integers/decimals
(on purpose) but we do not have to ask our parser for the number type, we can
just ask the jackson parser for a number representation of the value with the
right type.
Note that I did not add similar tests for big decimals because Jackson seems to
never return big decimals, even for decimal values that are out of the range of
values that can be represented by doubles.
Closes#11508
The mem section was buggy in cluster stats and removed. It is now added back with the same structure as in node stats, containing total memory, available memory, used memory and percentages. All the values are the sum of all the nodes across the cluster (or at least the ones that we were able to get the values from).
If elasticsearch controls the ID values as well as the documents
version we can optimize the code that adds / appends the documents
to the index. Essentially we an skip the version lookup for all
documents unless the same document is delivered more than once.
On the lucene level we can simply call IndexWriter#addDocument instead
of #updateDocument but on the Engine level we need to ensure that we deoptimize
the case once we see the same document more than once.
This is done as follows:
1. Mark every request with a timestamp. This is done once on the first node that
receives a request and is fixed for this request. This can be even the
machine local time (see why later). The important part is that retry
requests will have the same value as the original one.
2. In the engine we make sure we keep the highest seen time stamp of "retry" requests.
This is updated while the retry request has its doc id lock. Call this `maxUnsafeAutoIdTimestamp`
3. When the engine runs an "optimized" request comes, it compares it's timestamp with the
current `maxUnsafeAutoIdTimestamp` (but doesn't update it). If the the request
timestamp is higher it is safe to execute it as optimized (no retry request with the same
timestamp has been run before). If not we fall back to "non-optimzed" mode and run the request as a retry one
and update the `maxUnsafeAutoIdTimestamp` unless it's been updated already to a higher value
Relates to #19813
* Params improvements to Cluster Health API wait for shards
Previously, the cluster health API used a strictly numeric value
for `wait_for_active_shards`. However, with the introduction of
ActiveShardCount and the removal of write consistency level for
replication operations, `wait_for_active_shards` is used for
write operations to represent values for ActiveShardCount. This
commit moves the cluster health API's usage of `wait_for_active_shards`
to be consistent with its usage in the write operation APIs.
This commit also changes `wait_for_relocating_shards` from a
numeric value to a simple boolean value `wait_for_no_relocating_shards`
to set whether the cluster health operation should wait for
all relocating shards to complete relocation.
* Addresses code review comments
* Don't be lenient if `wait_for_relocating_shards` is set
While removing an index isn't actually an alias action, if we add
an alias action that deletes an index then we can delete and index
and add an alias with the same name as the index atomically, in
the same cluster state update.
Closes#20064
This commit adds the support for exclusion filter to the response filtering (filter_path) feature. It changes the XContentBuilder APIs so that it now accepts two types of filters: inclusive and exclusive. Filters are no more String arrays but sets of String instead.
Adds an explicit recoverySource field to ShardRouting that characterizes the type of recovery to perform:
- fresh empty shard copy
- existing local shard copy
- recover from peer (primary)
- recover from snapshot
- recover from other local shards on same node (shrink index action)
This makes GET operations more consistent with `_search` operations which expect
`(stored_)fields` to work on stored fields and source filtering to work on the
`_source` field. This is now possible thanks to the fact that GET operations
do not read from the translog anymore (#20102) and also allows to get rid of
`FieldMapper#isGenerated`.
The `_termvectors` API (and thus more_like_this too) was relying on the fact
that GET operations would extract fields from either stored fields or the source
so the logic to do this that used to exist in `ShardGetService` has been moved
to `TermVectorsService`. It would be nice that term vectors do not rely on this,
but this does not seem to be a low hanging fruit.
The network types in use on a cluster can be useful information to have,
so this commit adds aggregate metrics for the network types in use in a
cluster to the cluster stats.
Relates #20144
This change adds a special field named _none_ that allows to disable the retrieval of the stored fields in a search request or in a TopHitsAggregation.
To completely disable stored fields retrieval (including disabling metadata fields retrieval such as _id or _type) use _none_ like this:
````
POST _search
{
"stored_fields": "_none_"
}
````
Today we do a lot of accounting inside the engine to maintain locations
of documents inside the transaction log. This is only needed to ensure
we can return the documents source from the engine if it hasn't been refreshed.
Aside of the added complexity to be able to read from the currently writing translog,
maintainance of pointers into the translog this also caused inconsistencies like different values
of the `_ttl` field if it was read from the tlog or not. TermVectors are totally different if
the document is fetched from the tranlog since copy fields are ignored etc.
This chance will simply call `refresh` if the documents latest version is not in the index. This
streamlines the semantics of the `_get` API and allows for more optimizations inside the engine
and on the transaction log. Note: `_refresh` is only called iff the requested document is not refreshed
yet but has recently been updated or added.

The payload option was introduced with the new completion
suggester implementation in v5, as a stop gap solution
to return additional metadata with suggestions.
Now we can return associated documents with suggestions
(#19536) through fetch phase using stored field (_source).
The additional fetch phase ensures that we only fetch
the _source for the global top-N suggestions instead of
fetching _source of top results for each shard.
Adds `warnings` syntax to the yaml test that allows you to expect
a `Warning` header that looks like:
```
- do:
warnings:
- '[index] is deprecated'
- quotes are not required because yaml
- but this argument is always a list, never a single string
- no matter how many warnings you expect
get:
index: test
type: test
id: 1
```
These are accessible from the docs with:
```
// TEST[warning:some warning]
```
This should help to force you to update the docs if you deprecate
something. You *must* add the warnings marker to the docs or the build
will fail. While you are there you *should* update the docs to add
deprecation warnings visible in the rendered results.
Today, when listing thread pools via the cat thread pool API, thread
pools are listed in a column-delimited format. This is unfriendly to
command-line tools, and inconsistent with other cat APIs. Instead,
thread pools should be listed in a row-delimited format.
Additionally, the cat thread pool API is limited to a fixed list of
thread pools that excludes certain built-in thread pools as well as all
custom thread pools. These thread pools should be available via the cat
thread pool API.
This commit improves the cat thread pool API by listing all thread pools
(built-in or custom), and by listing them in a row-delimited
format. Finally, for each node, the output thread pools are sorted by
thread pool name.

Before this commit when an index pattern is used to filter the cluster state, only indices metadata are populated and routing table is just empty. This commit aligns the behavior of the filtering of cluster state's routing table with the filtering of cluster state's metadata so that coherent data are returned for both routing table & metadata when index pattern is requested.
This adds an extra REST handler for "_ingest/pipeline" so that users do not need to supply "_ingest/pipeline/*" to get all of them.
- Also adds a teardown section to related REST-tests for ingest.
Performing the bulk request shown in #19267 now results in the following:
```
{"_index":"test","_type":"test","_id":"1","_version":1,"_operation":"create","forced_refresh":false,"_shards":{"total":2,"successful":1,"failed":0},"status":201}
{"_index":"test","_type":"test","_id":"1","_version":1,"_operation":"noop","forced_refresh":false,"_shards":{"total":2,"successful":1,"failed":0},"status":200}
```
When the request body is missing, all documents in the target index are counted.
As mentioned in #19422, the same should happen when the request body is an empty
json object. This is also the behaviour for the `_search` endpoint and the two
APIs should behave in the same way.
With #19140 we started persisting the node ID across node restarts. Now that we have a "stable" anchor, we can use it to generate a stable default node name and make it easier to track nodes over a restarts. Sadly, this means we will not have those random fun Marvel characters but we feel this is the right tradeoff.
On the implementation side, this requires a bit of juggling because we now need to read the node id from disk before we can log as the node node is part of each log message. The PR move the initialization of NodeEnvironment as high up in the starting sequence as possible, with only one logging message before it to indicate we are initializing. Things look now like this:
```

Needless to say, settings `node.name` explicitly still works as before.
The commit also contains some clean ups to the relationship between Environment, Settings and Plugins. The previous code suggested the path related settings could be changed after the initial Environment was changed. This did not have any effect as the security manager already locked things down.
making the test wait until all urgent requests are completed before
finishing, so that tear down can properly delete the created index

index behind.
In the lack of tests the analyzer.alias feature was pretty much not working
at all on current master. Issues like #19163 showed some serious problems for users
using this feature upgrading to an alpha version.
This change fixes the processing order and allows aliases to be set for
existing analyzers like `default`. This change also ensures that if `default`
is aliased the correct analyzer is used for `default_search` etc.

creation in the REST tests, as we no longer need it due
to index creation now waiting for active shard copies
before returning (by default, it waits for the primary of
each shard, which is the same as ensuring yellow health).
Relates #19450
Before returning, index creation now waits for the configured number
of shard copies to be started. In the past, a client would create an
index and then potentially have to check the cluster health to wait
to execute write operations. With the cluster health semantics changing
so that index creation does not cause the cluster health to go RED,
this change enables waiting for the desired number of active shards
to be active before returning from index creation.
Relates #9126
The Java API supports this while mostly used for tests it can also be useful in
production environments. For instance if something is automated like a settings change
and we execute some health right after it the settings update might have some consequences
like a reroute which hasn't been fully applied since the preconditions are not fulfilled yet.
For instance if not all shards started the settings update is applied but the reroute won't move
currently initializing shards like in the shrink API test. Sure this could be done by waiting for
green before but if the cluster moves shards due to some side-effects waiting for all events is
still useful. I also took the chance to add unittests to Priority.java

No need to match against yaml responses via regexes in REST tests, yaml responses can be properly parsed via ObjectPath instead. Few REST tests need to be updated accordingly.
This commits adds support for a `teardown` section that can be defined in REST tests to

deletion of indices and templates.
This commit fixes several NPEs caused by implicitly performing a get request for a document that exists with its _source disabled and then trying to access the source. Instead of causing an NPE the following queries will throw an exception with a "source disabled" message (similar behavior as if the document does not exist).:
- GeoShape query for pre-indexed shape (throws IllegalArgumentException)
- Percolate query for an existing document (throws IllegalArgumentException)
A Terms query with a lookup will ignore the document if the source does not exist (same as if the document does not exist).
GET and HEAD requests for the document _source will return a 404 if the source is disabled (even if the document exists).

This adds a get task API that supports GET /_tasks/${taskId} and
removes that responsibility from the list tasks API. The get task
API supports wait_for_complation just as the list tasks API does
but doesn't support any of the list task API's filters. In exchange,
it supports falling back to the .results index when the task isn't
running any more. Like any good GET API it 404s when it doesn't
find the task.
Then we change reindex, update-by-query, and delete-by-query to
persist the task result when wait_for_completion=false. The leads
to the neat behavior that, once you start a reindex with
wait_for_completion=false, you can fetch the result of the task by
using the get task API and see the result when it has finished.
Also rename the .results index to .tasks.
By default the number of searches msearch executes is capped by the number of
nodes multiplied with the default size of the search threadpool. This default can be
overwritten by using the newly added `max_concurrent_searches` parameter.
Before the msearch api would concurrently execute all searches concurrently. If many large
msearch requests would be executed this could lead to some searches being rejected
while other searches in the msearch request would succeed.
The goal of this change is to avoid this exhausting of the search TP.

This adds support for setting the refresh request parameter to
`wait_for` in the `index`, `delete`, `update`, and `bulk` APIs. When
`refresh=wait_for` is set those APIs will not return until their
results have been made visible to search by a refresh.
Also it adds a `forced_refresh` field to the response of `index`,
`delete`, `update`, and to each item in a bulk response. This will
be true for requests with `?refresh` or `?refresh=true` and will be
true for some requests (see below) with `refresh=wait_for` but ought
to otherwise always be false.
`refresh=wait_for` is implemented as a list of
`Tuple<Translog.Location, Consumer<Boolean>>`s in the new `RefreshListeners`
class that is managed by `IndexShard`. The dynamic, index scoped
`index.max_refresh_listeners` setting controls a maximum number of
listeners allowed in any shard. If more than that many listeners
accumulate in the engine then a refresh will be forced, the thread that
adds the listener will be blocked until the refresh completes, and then the
listener will be called with a `forcedRefresh` flag so it knows that it was
the "straw that broke the camel's back". These listeners are only used by
`refresh=wait_for` and that flag manifests itself as `forced_refresh` being
`true` in the response.
About half of this change comes from piping async-ness down to the appropriate
layer in a way that is compatible with the ongoing with with sequence ids.

between the WriteResults.

Preserve `?refresh` behavior

Author: Nik Everett <nik9000@gmail.com>
Date: Wed Jun 1 17:39:05 2016 -0400
Handle hanging documents
If a document is added to the index during a refresh we weren't properly
firing its refresh listener. This happened because the way we detect
whether a refresh makes something visible or not is imperfect. It is
ok because it always errs on the side of thinking that something isn't
yet visible.
So when a document arrives during a refresh the refresh listeners
won't think it made it into a refresh when, often, it does. The way
we work around this is by telling Elasticsearch that it ought to
trigger a refresh if there are any pending refresh listeners even
if there aren't pending documents to update. Lucene short circuits
the refresh so it doesn't take that much effort, but the refresh
listeners still get the signal that a refresh has come in and they
still pick up the change and notify the listener.
This means that the time that a listener can wait is actually slightly
longer than the refresh interval.

Remove Translog#lastWriteLocation
I wasn't being careful enough with locks so it wasn't right anyway.
Instead this builds a synthetic Tranlog.Location when you call
getWriteLocation with much more relaxed equality guarantees. Rather
than being equal to the last Translog.Location returned it is
simply guaranteed to be greater than the last translog returned
and less than the next.

Move refresh listeners into their own class
They still live at the IndexShard level but they live on their
own in RefreshListeners which interacts with IndexShard using a
couple of callbacks and a registration method. This lets us test
the listeners without standing up an entire IndexShard. We still
test the listeners against an InternalEngine, because the interplay
between InternalEngine, Translog, and RefreshListeners is complex
and important to get right.

Never reply to replica actions while you have the operation lock
This last thing was causing periodic test failures because we were
replying while we had the operation lock. Now, we probably could get
away with that in most cases but the tests don't like it and it isn't
a good idea to do network io while you have a lock anyway. So this
prevents it.

Don't finish early if the primary finishes early
We use a "fake" pending shard that we resolve when the replicas have
all started.

Make performOnPrimary asyncS
Instead of returning Tuple<Response, ReplicaRequest> it returns
ReplicaRequest and takes a ActionListener<Response> as an argument.
We call the listener immediately to preserve backwards compatibility
for now.

Create ReplicatedMutationRequest
Superclass for index, delete, and bulkShard requests.

Create TransportReplicatedMutationAction
It is the superclass of replication actions that mutate data: index, delete,
and shardBulk. shardFlush and shardRefresh are replication actions but they
do not extend TransportReplicatedMutationAction because they don't change
the data, only shuffle it around.
If this option is enabled on a processor it silently catches any processor related failure and continues executing the rest of the pipeline.
Closes#18493
This adds a low level primitive operations to shrink an existing
index into a new index with a single shard. This primitive expects
all shards of the source index to allocated on a single node. Once the target index is initializing on the shrink node it takes a snapshot of the source index shards and copies all files into the target indices data folder. An [optimization](https://issues.apache.org/jira/browse/LUCENE-7300) coming in Lucene 6.1 will also allow for optional constant time copy if hard-links are supported by the filesystem. All mappings are merged into the new indexes metadata once the snapshots have been taken on the merge node.
To shrink an existing index all shards must be moved to a single node (one instance of each shard) and the index must be read-only:
```BASH
$ curl -XPUT 'http://localhost:9200/logs/_settings' -d '{
"settings" : {
"index.routing.allocation.require._name" : "shrink_node_name",
"index.blocks.write" : true
}
}
```
once all shards are started on the shrink node. the new index can be created via:
```BASH
$ curl -XPUT 'http://localhost:9200/logs/_shrink/logs_single_shard' -d '{
"settings" : {
"index.codec" : "best_compression",
"index.number_of_replicas" : 1
}
}'
```
This API will perform all needed check before the new index is created and selects the shrink node based on the allocation of the source index. This call returns immediately, to monitor shrink progress the recovery API should be used since all copy operations are reflected in the recovery API with byte copy progress etc.
The shrink operation does not modify the source index, if a shrink operation should
be canceled or if the shrink failed, the target index can simply be deleted and
all resources are released.
Closed indices are already displayed when no indices are explicitly selected. This commit ensures that closed indices are also shown when wildcard filtering is used. It also addresses another issue that is caused by the fact that the cat action is based internally on 3 different cluster states (one when we query the cluster state to get all indices, one when we query cluster health, and one when we query indices stats). We currently fail the cat request when the user specifies a concrete index as parameter that does not exist. The implementation works as intended in that regard. It checks this not only for the first cluster state request, but also the subsequent indices stats one. This means that if the index is deleted before the cat action has queried the indices stats, it rightfully fails. In case the user provides wildcards (or no parameter at all), however, we fail the indices stats as we pass the resolved concrete indices to the indices stats request and fail to distinguish whether these indices have been resolved by wildcards or explicitly requested by the user. This means that if an index has been deleted before the indices stats request gets to execute, we fail the overall cat request. The fix is to let the indices stats request do the resolving again and not pass the concrete indices.
Closes#16419Closes#17395
Significant changes:
* AbstractQueryTestCase has moved to the test framework module, in order for query builder tests in modules and plugins
* Added support to AbstractQueryTestCase to register plugins
* Lift the restriction that only one percolator could be added per index. This validation existed in MapperService, but because the percolator moved to a module it could no longer exist there. Instead of bringing it back it was removed. This validation existed since the percolator cache only supported one percolator query per document, since the percolator cache has been removed this restriction could removed as well.
* While moving percolator tests to the new module, also removed a couple of tests for the deprecated percolate and mpercolate api. These APIs are now sugar APIs for bwc and rediect to the searvh and msearvh APIs. Some tests were still testing as if percolate and mpercolate API did the percolation, but this no longer the case and these tests could be removed.
Today if a shard fails during initialization phase due to misconfiguration, broken disks,
missing analyzers, not installed plugins etc. elasticsaerch keeps on trying to initialize
or rather allocate that shard. Yet, in the worst case scenario this ends in an endless
allocation loop. To prevent this loop and all it's sideeffects like spamming log files over
and over again this commit adds an allocation decider that stops allocating a shard that
failed more than N times in a row to allocate. The number or retries can be configured via
`index.allocation.max_retry` and it's default is set to `5`. Once the setting is updated
shards with less failures than the number set per index will be allowed to allocate again.
Internally we maintain a counter on the UnassignedInfo that is reset to `0` once the shards
has been started.

Before 5.0 for it was required that the percolator queries were cached in jvm heap as Lucene queries for two reasons:
1) Performance. The percolator evaluated all percolator queries all the time. There was no pre-selecting queries that are likely to match like we have today.
2) Updates made to percolator queries were visible in realtime, Today these changes are visible in near realtime. So updating no longer requires the percolator to have the queries in jvm heap.
So having the percolator queries in jvm heap via the percolator cache is now less attractive. Especially when there are many percolator queries then these queries can consume many GBs of jvm heap.
Removing the percolator cache does make the percolate query slower compared to how the execution time in 5.0.0-alpha1 and alpha2, but it is still faster compared to 2.x and before.
Sorts an array of values in ascending or descending order. If all elements are numerics, they will be sorted numerically. If values are strings, or mixtures of strings/numbers, the elements will be sorted lexicographically.
Currently terms on an ip address try to put their binary representation in the
json response. With this commit, they would return a formatted ip address:
```
"buckets": [
{
"key": "192.168.1.7",
"doc_count": 1
}
]
```
All other values are errors.
Add java test for throttling. We had a REST test but it only ran against
one node so it didn't catch serialization errors.
Add Simple round trip test for rethrottle request
* Add isSearchable and isAggregatable (collapsed to true if any of the instances of that field are searchable or aggregatable).
* Accept wildcards in field names.
* Add a section named conflicts for fields with the same name but with incompatible types (instead of throwing an exception).
The url that takes an id has a trailing forward slash, not really an
error but as its the only url in the whole spec that does this it
triggered my OCD :)
* `rename` processor, renamed `to` to `target_field`
* `date` processor, renamed `match_field` to `field` and renamed `match_formats` to `formats`
* `geoip` processor, renamed `source_field` to `field` and renamed `fields` to `properties`
* `attachment` processor, renamed `source_field` to `field` and renamed `fields` to `properties`
Closes#17835
* Added an extra `field` parameter to the `percolator` query to indicate what percolator field should be used. This must be an existing field in the mapping of type `percolator`.
* The `.percolator` type is now forbidden. (just like any type that starts with a `.`)
This only applies for new indices created on 5.0 and later. Indices created on previous versions the .percolator type is still allowed to exist.
The new `percolator` field type isn't active in such indices and the `PercolatorQueryCache` knows how to load queries from these legacy indices.
The `PercolatorQueryBuilder` will not enforce that the `field` parameter is of type `percolator`.
We advertise in our documentation that byte units are like `kb`, `mb`... But we actually only support the simple notation `k` or `m`.
This commit adds support for the documented form and keeps the non documented options to avoid any breaking change.
It also adds support for `micros`, `nanos` and `d` as a time unit in `_cat` API.
Remove the support for `b` as a SizeValue unit. Actually, for numbers, when using raw numbers without unit, there is no text to add/parse after the number. For example, you don't write `10` as `10b`. We support option like `size=` in `_cat` API which means that we want to display raw data without unit (singles).
Documentation updated accordingly.
Add test for the empty size option.
Fix missing TimeValues options for some cat APIs
Running `gradle install` on the rest-api-spec fails because there is no available install
task. This change applies the nexus plugin so that we can install and should also enable
publishing as part of the uploadArchives task.
If ts=0, cat health disable epoch and timestamp
Be Constant String timestamp and epoch
Move timestamp and epoch to Table
Add rest-api test and test

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.
`text` fields will have fielddata disabled by default. Fielddata can still be
enabled on an existing index by setting `fielddata=true` in the mappings.
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"
} ]
},
"PzdyMZGXQdGhqTJHF_hGgA" : {
"node_name" : "The Symbiote",
"node_attributes" : { },
"final_decision" : "NO",
"weight" : 2.3166666,
"decisions" : [ {
"decider" : "filter",
"decision" : "NO",
"explanation" : "node does not match index include filters [foo:\"bar\"]"
} ]
}
}
}
```
And when the shard *is* assigned, the output looks like:
```
{
"shard" : {
"index" : "only-foo",
"index_uuid" : "KnW0-zELRs6PK84l0r38ZA",
"id" : 0,
"primary" : true
},
"assigned" : true,
"assigned_node_id" : "Qc6VL8c5RWaw1qXZ0Rg57g",
"nodes" : {
"V-Spi0AyRZ6ZvKbaI3691w" : {
"node_name" : "Susan Storm",
"node_attributes" : {
"bar" : "baz"
},
"final_decision" : "NO",
"weight" : 1.4499999,
"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" : "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.
Resolves#14593
In #17198, we removed suggest transport action, which
used the `suggest` threadpool to execute requests. Now
`suggest` threadpool is unused and suggest requests are
executed on the `search` threadpool.
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 '{
"index.number_of_shards" : "1",
"index.query.default_field" : "main_field",
"index.translog.durability" : "async",
"index.ttl.disable_purge" : "true"
}'
*************************************************************************************
```
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:
Closes#10741Closes#7297Closes#13176Closes#13978Closes#11264Closes#10741Closes#4317
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.
