Today we can execute cluster API actions on only master, data or ingest nodes
using the `master:true`, `data:true` and `ingest:true` filters, but it is not
so easy to select coordinating-only nodes (i.e. those nodes that are neither
master nor data nor ingest nodes). This change fixes this by adding support for
a `coordinating_only` filter such that `coordinating_only:true` adds all
coordinating-only nodes to the set of selected nodes, and
`coordinating_only:false` deletes them.
Resolves#28831.
This is a follow-up to our previous change to only fork javac if needed
to respect the Java compiler home (via JAVA_HOME). This commit makes the
same change for groovyc: we only fork groovyc if the JDK for Gradle is
not the JDK specified for the compiler (via JAVA_HOME).
We've been setting this value to 500ms in the default low-level REST
client configuration, misunderstanding the effect that it would have.
This proved very problematic, as it ends up causing `TimeoutException`
returned from the leased pool in some cases even for successful requests.
Closes#24069
The HTTPClient used in watcher is based on the apache http client. The
current client is using a lot of defaults - which are not always
optimal. Two of those defaults are the maximum number of total
connections and the maximum number of connections to a single route.
If one of those limits is reached, the HTTPClient waits for a connection
to be finished thus acting in a blocking fashion. In order to prevent
this when many requests are being executed, we increase the limit of
total connections as well as the connections per route (a route is
basically an endpoint, which also contains proxy information, not
containing an URL, just hosts).
On top of that an additional option has been set to evict
long running connections, which can potentially be reused after some
time. As this requires an additional background thread, this required
some changes to ensure that the httpclient is closed properly. Also the
timeout for this can be configured.
We started forking javac to avoid GC overhead when running builds. Yet,
we do not seem to have this problem anymore and not forking leads to a
substantial speed improvement. This commit stops forking javac.
Deprecate the many arguments versions of `performRequest` and
`performRequestAsync` in favor of the `Request` object flavored variants
introduced in #29623. We'll be dropping the many arguments variants in
7.0 because they make it difficult to add new features in a backwards
compatible way and they create a *ton* of intellisense noise.
We had been using `task_id:1` or `taskId:1` because it is parses as a
valid task identifier but the `:1` part is confusing. This replaces
those examples with `task_id` which matches the response from the list
tasks API.
Closes#28314
This commit renames IndexLifecycleManager to SecurityIndexManager as it
is not actually a general purpose class, but specific to security. It
also removes indirection in code calling the lifecycle service, instead
calling the security index manager directly.
Fixes and edge case when using `more_like_this` where TermVectorsWriter
could throw an NPE when a field produced zero tokens after analysis. This
changes the implementation to use an empty list of tokens in this case.
Closes#30148
Adds a description of the most important subdirectories to
`CONTRIBUTING.md` to help folks that are less familiar with the project
get their bearings. It reflects that state of the project right now so
it will inevitably go out of date. But I'll try and keep it up to date.
Auto-expands replicas in the same cluster state update (instead of a follow-up reroute) where nodes are added or removed.
Closes#1873, fixing an issue where nodes drop their copy of auto-expanded data when coming up, only to sync it again later.
Adds verification that geohashes are not empty and contain only
valid characters. It fixes the issue when en empty geohash is
treated as [-180, -90] and geohashes with non-geohash character
are getting resolved into invalid coordinates.
Closes#23579
Starting watcher should wait for the watcher to be started before
marking the status as started, which is now done via a callback.
Also, reloading watcher could set the execution service to paused. This could
lead to watches not being executed, when run in tests. This fix does not
change the paused flag in the execution service, just clears out the
current queue and executions.
Closes#30381
That PR changed the execution path of index settings default to be on the master
until the PR is back-ported the old master will not return default settings.
When deleting or creating a snapshot for a given shard, elasticsearch
usually starts by listing all the existing snapshotted files in the repository.
Then it computes a diff and deletes the snapshotted files that are not
needed anymore. During this deletion, an exception is thrown if the file
to be deleted does not exist anymore.
This behavior is challenging with cloud based repository implementations
like S3 where a file that has been deleted can still appear in the bucket for
few seconds/minutes (because the deletion can take some time to be fully
replicated on S3). If the deleted file appears in the listing of files, then the
following deletion will fail with a NoSuchFileException and the snapshot
will be partially created/deleted.
This pull request makes the deletion of these files a bit less strict, ie not
failing if the file we want to delete does not exist anymore. It introduces a
new BlobContainer.deleteIgnoringIfNotExists() method that can be used
at some specific places where not failing when deleting a file is
considered harmless.
Closes#28322
The test indexes new documents and is thus correct in testing that the response result
is `CREATED`. Sadly we can't guarantee exactly once delivery just yet.
Relates #9967Closes#21658
Today when processing a request for a URL path for which we can not find
a handler we send back a plain-text response. Yet, we have the accept
header in our hand and can respect the accepted media type of the
request. This commit addresses this.
This change adds a new plugin called `analysis-nori` that exposes
Korean text analysis in es using the new Lucene Korean analyzer module named (`nori`).
The plugin adds:
* a Korean analyzer: `nori`
* a Korean tokenizer: `nori_tokenizer`
* a part of speech stop filter: `nori_part_of_speech`
* a filter that can replace Hanja characters with their Hangul transcription: `nori_readingform`
This commit removes the unnecessary transport_client cluster permission
from the role that is used as an example in our documentation. This
permission is not needed to use cross cluster search.
When validating the search request, we make sure any date_histogram
aggregations have timezones that match the jobs. But we didn't
do any such validation on range queries.
While it wouldn't produce incorrect results, it would be confusing
to the user as no documents would match the aggregation (because we
add a filter clause on the timezone for the agg).
Now the user gets an exception up front, and some helpful text about
why the range query didnt match, and which timezones are acceptable
Changes how data is read from CipherInputStream
Instead of using `read()` and checking that the bytes read are what we
expect, use `readFully()` which will read exactly the number of bytes
while keep reading until the end of the stream or throw an
`EOFException` if not all bytes can be read.
This approach keeps the simplicity of using CipherInputStream while
working as expected with both JCE and BCFIPS Security Providers
This commit updates the multi cluster search test with security so that
the user that is simply performing a multi cluster search does not have
any cluster permissions. This is done as none are needed by this user
and excess privileges could mask a behavior change.
This PR adds support for the Get Settings API to the java high-level rest client.
Furthermore, logic related to the retrieval of default settings has been moved from the rest layer into the transport layer and now default settings may be retrieved consistency via both the rest API and the transport API.
