Notes that you should increase the `indices.query.bool.max_clause_count`
setting if you increase the `index.mapping.total_fields.limit`
setting.
Closes#46928.
Today if an Elasticsearch node reaches a disk watermark then it will repeatedly
emit logging about it, which implies that some action needs to be taken by the
administrator. This is misleading. Elasticsearch strives to keep nodes under
the high watermark, but it is normal to have a few nodes occasionally exceed
this level. Nodes may be over the low watermark for an extended period without
any ill effects.
This commit enhances the logging emitted by the `DiskThresholdMonitor` to be
less misleading. The expected case of hitting the high watermark and
immediately relocating one or more shards that to bring the node back under the
watermark again is reduced in severity to `INFO`. Additionally, `INFO` messages
are not emitted repeatedly.
Fixes#48038
Today our instructions in `CONTRIBUTING.md` regarding license headers are a
little unclear. This commit clarifies the exact headers that are required for
contributions.
The logic for handling empty segment files has been
unnecessary ever since #24021 which removes the support
for these files in 6.x -> we can safely remove the
support for restoring these from 7.x+ to simplify the code.
* Create an upload report once the build completes
We used to have this logic in Jenkins, but that forced us to make it
platform dependent and gave us less control on what to include here.
With this change we create a single archive to be uploaded after the
build completes, and we include a link in the build scan to where we
know this should get uploaded.
* Fix when there's nothign to upload
* Log the directory size
* Switch to ant to walk the project tree
* Collect journlas
* Filter for regular files
* only call journalctl on unix where we have bash
* Grab only logs fro this gradle version
* restrict demon log to relevant one
* Slow log must use separate underlying logger for each index (#47234)
SlowLog instances should not share the same underlying logger, as it would cause different indexes override each other levels. When creating underlying logger, unique per index identifier should be used. Name + IndexSettings.UUID
Closes#42432
There is no reason to still resolve the
fallback `IndexId` here. It only applies to
`2.x` repos and those we can't read anymore
anyway because they use an `/index` instead of
an `/index-N` blob at the repo root for which
at least 7.x+ does not contain the logic to find
it.
If a job stops right after reindexing is finished but before
we refresh the destination index, we don't refresh at all.
If the job is started again right after, it jumps into the analyzing state.
However, the data is still not searchable.
This is why we were seeing test failures that we start the process
expecting X rows (where X is lower than the expected number of docs)
and we end up getting X+.
We fix this by moving the refresh of the dest index right before
we start the process so it always ensures the data is searchable.
Closes#47612
Backport of #48090
Several links from the ILM HLRC Javadoc to the online documentation were
not updated when the ILM HLRC documentation was written. This commit
fixes those links.
Adds `GET /_script_context`, returning a `contexts` object with each
available context as a key whose value is an empty object. eg.
```
{
"contexts": {
"aggregation_selector": {},
"aggs": {},
"aggs_combine": {},
...
}
}
```

This test has been failing very frequently on Windows checks for 7.4. We've also seen it for 7.x as well as for the new 7.5 tests. I'm muting during investigation so we can see if this is masking any other issues.
The after snapshot action is interfering with SLM deleting snapshots
here it seems, causing concurrent delete exceptions.
Since these tests are now test-scoped there is no reason to run
snapshot deletes after each test so we can remove them to avoid this issue.
Closes#47937
We were not closing repositories on Node shutdown.
In production, this has little effect but in tests
shutting down a node using `MockRepository` and is
currently stuck in a simulated blocked-IO situation
will only unblock when the node's threadpool is
interrupted. This might in some edge cases (many
snapshot threads and some CI slowness) result
in the execution taking longer than 5s to release
all the shard stores and thus we fail the assertion
about unreleased shard stores in the internal test cluster.
Regardless of tests, I think we should close repositories
and release resources associated with them when closing
a node and not just when removing a repository from the CS
with running nodes as this behavior is really unexpected.
Fixes#47689
* Add SLM support to xpack usage and info APIs
This is a backport of #48096
This adds the missing xpack usage and info information into the
`/_xpack` and `/_xpack/usage` APIs. The output now looks like:
```
GET /_xpack/usage
{
...
"slm" : {
"available" : true,
"enabled" : true,
"policy_count" : 1,
"policy_stats" : {
"retention_runs" : 0,
...
}
}
```
and
```
GET /_xpack
{
...
"features" : {
...
"slm" : {
"available" : true,
"enabled" : true
},
...
}
}
```
Relates to #43663
* Fix missing license
This PR fixes (#47593). Stored scripts with the old-style id of lang#id are
saved through the upgrade process but are no longer accessible in recent
versions. This fix will drop those scripts altogether since there is no way for
a user to access them.
* Update testing document for new packaging tests
The TESTING.asciidoc document had gotten out of date due to some new and
wonderful changes in our vagrant testing code. I've removed all of the
instructions that no longer work, and added working examples and descriptions
in their place.
This adds parsing an inference model as a possible
result of the analytics process. When we do parse such a model
we persist a `TrainedModelConfig` into the inference index
that contains additional metadata derived from the running job.
Today the docs say that the low watermark has no effect on any shards that have
never been allocated, but this is confusing. Here "shard" means "replication
group" not "shard copy" but this conflicts with the "never been allocated"
qualifier since one allocates shard copies and not replication groups.
This commit removes the misleading words. A newly-created replication group
remains newly-created until one of its copies is assigned, which might be quite
some time later, but it seems better to leave this implicit.
Previously when a numeric literal was enclosed in parentheses and then
negated, the negation was lost and the number was considered positive, e.g.:
`-(5)` was considered as `5` instead of `-5`
`- ( (1.28) )` was considered as `1.28` instead of `-1.28`
