This commit rewords the note on whitespace in Log4j settings to not
refer to only of the examples on the page, but instead be clear that the
note applies to all the examples on the page.
A confusing thing that can happen when configuring Log4j is that
extraneous whitespace throws off its configuration parsing yet the error
messages that arise give no indication that this is the problem. This
commit adds a note to the docs.

Start moving built in analysis components into the new analysis-common
module. The goal of this project is:
1. Remove core's dependency on lucene-analyzers-common.jar which should
shrink the dependencies for transport client and high level rest client.
2. Prove that analysis plugins can do all the "built in" things by moving all
"built in" behavior to a plugin.
3. Force tests not to depend on any oddball analyzer behavior. If tests
need anything more than the standard analyzer they can use the mock
analyzer provided by Lucene's test infrastructure.
This commit removes the deprecated cloud.aws.* settings. It also removes
backcompat for specifying `discovery.type: ec2`, and unused aws signer
code which was removed in a previous PR.
This commit adds a call to jstack to see where each node is stuck when
starting up, if a timeout occurs. This also decreases the timeout back
to 30 seconds.
This leniency was left in after plugin installer refactoring for 2.0
because some tests still relied on it. However, the need for this
leniency no longer exists.
Unlike other implementations of InternalNumericMetricsAggregation.SingleValue,
the InternalBucketMetricValue aggregation currently doesn't implement a
specialized interface that exposes the `keys()` method. This change adds this so
that clients can access the keys via the interface.
This change adds an index setting to define how the documents should be sorted inside each Segment.
It allows any numeric, date, boolean or keyword field inside a mapping to be used to sort the index on disk.
It is not allowed to use a `nested` fields inside an index that defines an index sorting since `nested` fields relies on the original sort of the index.
This change does not add early termination capabilities in the search layer. This will be added in a follow up.

Elasticsearch runs as user elasticsearch with uid:gid 1000:1000 inside
the Docker container. Clarify that bind mounted local directories need
to be accessible by this user.

* Replicate write failures
Currently, when a primary write operation fails after generating
a sequence number, the failure is not communicated to the replicas.
Ideally, every operation which generates a sequence number on primary
should be recorded in all replicas.
In this change, a sequence number is associated with write operation
failure. When a failure with an assinged seqence number arrives at a
replica, the failure cause and sequence number is recorded in the translog
and the sequence number is marked as completed via executing `Engine.noOp`
on the replica engine.
* use zlong to serialize seq_no
* Incorporate feedback
* track write failures in translog as a noop in primary
* Add tests for replicating write failures.
Test that document failure (w/ seq no generated) are recorded
as no-op in the translog for primary and replica shards
* Update to master
* update shouldExecuteOnReplica comment
* rename indexshard noop to markSeqNoAsNoOp
* remove redundant conditional
* Consolidate possible replica action for bulk item request
depanding on it's primary execution
* remove bulk shard result abstraction
* fix failure handling logic for bwc
* add more tests
* minor fix
* cleanup
* incorporate feedback
* incorporate feedback
* add assert to remove handling noop primary response when 5.0 nodes are not supported
`script_stack` is super useful when debugging Painless scripts
because it skips all the "weird" stuff involved that obfuscates
where the actual error is. It skips Painless's internals and
call site bootstrapping.
It works fine, but it didn't have many tests. This converts a
test that we had for line numbers into a test for the
`script_stack`. The line numbers test was an indirect test
for `script_stack`.
This change simplifies how the rest test runner finds test files and
removes all leniency. Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.

The `maxUnsafeAutoIdTimestamp` timestamp is a safety marker guaranteeing that no retried-indexing operation with a higher auto gen id timestamp was process by the engine. This allows us to safely process documents without checking if they were seen before.
Currently this property is maintained in memory and is handed off from the primary to any replica during the recovery process.
This commit takes a more natural approach and stores it in the lucene commit, using the same semantics (no retry op with a higher time stamp is part of this commit). This means that the knowledge is transferred during the file copy and also means that we don't need to worry about crazy situations where an original append only request arrives at the engine after a retry was processed *and* the engine was restarted.
Today when we merge hits we have a hard check to prevent AIOOB exceptions
that simply skips an expected search hit. This can only happen if there is a
bug in the code which should be turned into a hard exception or an assertion
triggered. This change adds an assertion an removes the lenient check for the
fetched hits.
Some aggregations (like Min, Max etc) use a wrong DocValueFormat in
tests (like IP or GeoHash). We should not test aggregations that expect
a numeric value with a DocValueFormat like IP. Such wrong DocValueFormat
can also prevent the aggregation to be rendered as ToXContent, and this
will be an issue for the High Level Rest Client tests which expect to be
able to parse back aggregations.
We'd like to be able to support context-sensitive whitelists in
Painless but we can't now because the whitelist is a static thing.
This begins to de-static the whitelist, in particular removing
the static keyword from most of the methods on `Definition` and
plumbing the static instance into the appropriate spots as though
it weren't static. Once we de-static all the methods we should be
able to fairly simply build context-sensitive whitelists.
The only "fun" bit of this is that I added another layer in the
chain of methods that bootstraps `def` calls. Instead of running
`invokedynamic` directly on `DefBootstrap` we now `invokedynamic`
`$bootstrapDef` on the script itself loads the `Definition` that
the script was compiled against and then calls `DefBootstrap`.
I chose to put `Definition` into `Locals` so I didn't have to
change the signature of all the `analyze` methods. I could have
do it another way, but that seems ok for now.
We want to upgrade to Lucene 7 ahead of time in order to be able to check whether it causes any trouble to Elasticsearch before Lucene 7.0 gets released. From a user perspective, the main benefit of this upgrade is the enhanced support for sparse fields, whose resource consumption is now function of the number of docs that have a value rather than the total number of docs in the index.
Some notes about the change:
- it includes the deprecation of the `disable_coord` parameter of the `bool` and `common_terms` queries: Lucene has removed support for coord factors
- it includes the deprecation of the `index.similarity.base` expert setting, since it was only useful to configure coords and query norms, which have both been removed
- two tests have been marked with `@AwaitsFix` because of #23966, which we intend to address after the merge
Checks that IndicesClusterStateService stays consistent with incoming cluster states that contain no_master blocks (especially
discovery.zen.no_master_block=all which disables state persistence). In particular this checks that active shards which have no in-memory data
structures on a node are failed.
This changes the trace level logging to warn, and adds the needed number to the message as well.
My fear is that it may get noisy, but this is an issue that you want to be noisy.
The docs don't clearly explain that the deleted doc count also comes from lucene.
IMHO, it is worth highlighting this information separately, as a Note.
Apart from that, there should be an official recommended alternative as well.
After splitting integ tests into cluster configuration and the test
runner task, we still have dependencies of the test runner added as deps
of the cluster. This commit adds dependencies directly to the cluster,
so that the runner can have other dependencies independent of what is
needed for the cluster.
