We have to set the recovery setting to `0` if we don't want throttling
from recoveries. Otherwise the randomized value used for this setting in
tests can lead to throttling unexpectedly.
Closes#61311
With #60683 we stopped forcing aggregating all docs using a single
Aggregator which made some of our accuracy assumptions about the stats
aggregator incorrect. This adds a test that does the forcing and asserts
the old accuracy and adds a test without the forcing with much looser
accuracy guarantees.
Closes#61132
The FieldNamesFieldMapper field has different behaviour for indexes created in
clusters earlier than v6.1, and the code to deal with this was still using the vestigial
FieldType field of FieldMapper in its indexing path. This meant that documents
added after an upgrade were not correctly indexing their field names field. This
commit corrects the parseCreateField method to use the default field type.
Fixes#61305
Today a common reason for a `ShardLockObtainFailedException` is when a
shard is removed from a node and then assigned straight back to it again
before the node has had a chance to shut the previous shard instance
down. For instance, this can happen if a node briefly leaves the cluster
holding a primary with no in-sync replicas.
The message in this case is typically as follows:
obtaining shard lock timed out after 5000ms, previous lock details: [shard creation] trying to lock for [shard creation]
This is pretty hard to interpret, and doesn't raise the important
question: "why didn't the shard shut down sooner?"
With this change we reword the message a bit, report the age of the
shard lock, and adjust the details to report that the lock is held by a
closing shard:
obtaining shard lock for [starting shard] timed out after [5000ms], lock already held for [closing shard] with age [12345ms]
Relates #38807
`ESTestCase#testRandomDateFormatterPattern` previously asserted that
round tripping `millis -> text -> millis` wouldn't lose any precision.
But some date formats don't include the time of day so, of course, this
could lose precision. This replaces that with an assertion that
`text -> millis -> text` doesn't lose precision. Which should be true
for any sane date format. Really, we're just trying to make sure that
the random date formats that we return are *fairly* sane.
We have seen a situation where the total search operations are higher
than expected. Unfortunately, we did not have enough info to figure it
out. This commit adds the failures to the error to provide more context
and adjusts the log level in case of failure to debug.
Per #35284, it looks like we changed this from a max field expansions limit to a soft limit using the `indices.query.bool.max_clause_count` dynamic cluster settting.
We only work with heap byte buffers at this point and those we can and do unwrap the
`byte[]` ourselves and use `BytesArray` instead of a needless level of indirection via `ByteBuffer`.
Backport of #60742.
This PR resurrects support for building Docker images based on one of
Red Hat's UBI images. It also adds support for running the existing
Docker tests against the image. The image is named
`elasticsearch-ubi8:<version>`.
I also changed the Docker build file uses enums instead strings in a lot
of places, for added rigour.
There is a corner case here in which during partial snapshot the index is
deleted right between starting the snapshot in the CS and the data node getting to work
on it, causing the data node the fail that shard snapshot and making the snapshot `PARTIAL`.

Adds an important admonition for the built-in `metrics-*-*` and `logs-*-*` index
templates.
Updates several put index template snippets to include a priority.
Adds a method to make a random date `DateFormatter` pattern. We expect
this'll be useful for runtime fields to compate their formatting with
the standard date field.
Currently we occasionally can get ArithmeticException from parsing bad input
values on 'date' fields that are passed on even if 'ignore_malformed' is set.
This change adds this exception to the ones we already catch for malformed
values.
Closes#52634
* Some progress on failing runtime fields tests (bring #61098 to 7.x)
This breaks apart the a test for the `terms` aggregation into one that
work for runtime fields and one that doesn't.
Breaks up an integration test into one that runtime fields can run and
one that runtime fields have to skip. This is because runtime fields
don't have global ords and we assert things *about* global ords in the
test we have to skip.
