Today the PeerFinder silently updates the set of found peers as new peers are
discovered and old ones are disconnected, and elections are scheduled
independently of these changes. In fact, it would be better if the election
scheduler were only activated on discovery of a quorum of peers. This commit
introduces the `onFoundPeersUpdated` method that allows this flow.
An election requires a node to select a term that is higher than all
previously-seen terms. If nodes are too enthusiastic about starting elections
then they can effectively excludes itself from the cluster until the leader can
bump to a still-higher term, and if this process repeats then a single faulty
node can prevent the cluster from making useful progress.
The solution is to start the election with a pre-voting round to ensure that
there is at least a quorum of nodes who believe there to be no leader.
This also fixes up some merge issues.
* Modified a reference to real time to match the previous line reference of
realtime.
* Modified eg to e.g. as it's an abbreviation for the latin exempli gratia
* Added missing pronoun to `_executing_filters` section.
This is a followup to #31886. After that commit the
TransportConnectionListener had to be propogated to both the
Transport and the ConnectionManager. This commit moves that listener
to completely live in the ConnectionManager. The request and response
related methods are moved to a TransportMessageListener. That listener
continues to live in the Transport class.
* Lazy resolve DNS (i.e. `String` to `DiscoveryNode`) to not run into indefinitely caching lookup issues (provided the JVM dns cache is configured correctly as explained in https://www.elastic.co/guide/en/elasticsearch/reference/6.3/networkaddress-cache-ttl.html)
* Changed `InetAddress` type to `String` for that higher up the stack
* Passed down `Supplier<DiscoveryNode>` instead of outright `DiscoveryNode` from `RemoteClusterAware#buildRemoteClustersSeeds` on to lazy resolve DNS when the `DiscoveryNode` is actually used (could've also passed down the value of `clusterName = REMOTE_CLUSTERS_SEEDS.getNamespace(concreteSetting)` together with the `List<String>` of hosts, but this route seemed to introduce less duplication and resulted in a significantly smaller changeset).
* Closes#28858
- Missing links to new IndexCaps API
- Incorrect security permissions on IndexCaps API
- GetJobs API must supply a job (or `_all`), omitting throws error
- Link to search/agg limitations from RollupSearch API
- Tweak URLs in quick reference
- Formatting of overview page
As the multibucket feature was merged in, this test hit a side effect
which means buckets trailing an anomaly could become anomalous.
This commit fixes the problem by filtering low score records when
we request them.
Elasticsearch versions earlier than 6.4.0 cannot properly run in a
FIPS 140 JVM. This commit ensures that we use a non-FIPS JVM for
nodes that we spin up in BWC tests even when we're testing FIPS.
Currently, if geo context is represented by something other than
geo_point or an object with lat and lon fields, the parsing of it
as a geo context can result in ignoring the context altogether,
returning confusing errors such as number_format_exception or trying
to parse the number specifying as long-encoded hash code. It would also
fail if the geo_point was stored.
This commit makes the mapping parsing more strict and will fail during
mapping update or index creation if the geo context doesn't point to
a geo_point field.
Supersedes #32412Closes#32202
* ML: fix updating opened jobs scheduled events (#31651)
* Adding UpdateParamsTests license header
* Adding integration test and addressing PR comments
* addressing test and job names
* Scripted metric aggregations: add deprecation warning and system property to control legacy params
Scripted metric aggregation params._agg/_aggs are replaced by state/states context variables. By default the old params are still present, and a deprecation warning is emitted when Scripted Metric Aggregations are used. A new system property can be used to disable the legacy params. This functionality will be removed in a future revision.
* Fix minor style issue and docs test failure
* Disable deprecated params._agg/_aggs in tests and revise tests to use state/states instead
* Add integration test covering deprecated scripted metrics aggs params._agg/_aggs access
* Disable deprecated params._agg/_aggs in docs integration tests and revise stored scripts to use state/states instead
* Revert unnecessary migrations doc change
A relevant note should be added in the changes destined for 7.0; this PR is going to be backported to 6.x.
* Replace deprecated _agg param bwc integration test with a couple of unit tests
* Fix compatibility test after merge
* Rename backwards compatibility system property per code review feedback
* Tweak deprecation warning text per review feedback
This fix prevernts trying to parse unknown timezone ids by converting
the joda time zone via java.util.TimeZone to a java time based ZoneId.
Closes#32927
testDocStats test is flaky and sometimes it's failing on jenkins and
failure is not reproducible locally. The reason for this failure is in
timing. If the number of deleted documents is greater than 33% of inserted
documents, Lucene will schedule segments to merge if TieredMergePolicy is
used (it's not the case for LogMergePolicy, but ES is only using
TieredMergePolicy). If this merge is performed before stats are
retrieved - we will get 0 for "deleted" counter.
So basically this counter could be either 0 or numOfDeletedDocs at this point,
but this is the too loose assertion and we decided to remove it at all.
Closes#32766
It took me quite a while of online searching and experimenting to realize the function-call asymmetry in the Add versus Remove from a list, like the "tags" list! I realize we cannot give examples for every single thing the user wants to do in Painless, but this is such a common use case (removing a tag from a single doc, or from a set of docs with Update-By-Query) that I believe it ought to be demonstrated immediately after the "add a tag" example. We have an example of removing an entire document field, but not removing one element of a list (a multi-valued field).
Also, a minor grammar fix: I have added an apostrophe to the word "its" in the accompanying text of the example just above.
Add tests for build-tools to make sure example plugins build stand-alone using it.
This will catch issues such as referencing files from the buildSrc directly, breaking external uses of build-tools.
This commit removes the put privilege API in favor of having a single API to
create and update privileges. If we see the need to have an API like this in
the future we can always add it back.
The Kibana settings docs that these watches rely on can sometimes
contain no xpack settings. When this is the case, we will end up with a
null pointer exception in the script. We need to guard against in these
scripts so this commit does that.
Moves JoinTaskExecutor out of ZenDiscovery so that it can be reused for Zen2. Also ensures that tasks to JoinTaskExecutor have a proper identity, so that multiple tasks for the same node can coexist.
The docs here incorrectly state that it is okay for a heap dump file to
exist when heap dump path is configured to a fixed filename. This is
incorrect, the JVM will fail to write the heap dump if a heap dump file
already exists at the specified location (see the DumpWriter constructor
DumpWriter::DumpWriter(const char* path) in the JVM source).
This removes def from the classes map in PainlessLookup and instead always special
cases it. This prevents potential calls against the def type that shouldn't be made and
forces all cases of def throughout Painless code to be special cased.
This commit disables the automatic `refresh_interval` in order to ensure
that index readers cannot differ between the normal and scroll search.
This issue is related to the 7.5 Lucene upgrade which contains a change that
makes single segment merge more likely to occur (max deletes percentage).
Closes#32682
We do not support passphrases on the secure settings storage (the
keystore). Yet, we added support for this in the API layer. This commit
removes this support so that we are not limited in our future options,
or have to make a breaking change.
