This commit renames all rest test files to use the .yml extension
instead of .yaml. This way the extension used within all of
elasticsearch for yaml is consistent.
This commit adds gcs credential settings to the elasticsearch keystore.
The setting name follows the same pattern as the s3 client settings,
beginning with `gcs.client.`, followed by the client name, and then the
setting name, in this case, `credentials_file`. Using the legacy service
file setting is also deprecated.
When constructing an array list, if we know the size of the list in
advance (because we are adding objects to it derived from another list),
we should size the array list to the appropriate capacity in advance (to
avoid resizing allocations). This commit does this in various places.

This commit documents how to write a `ScriptEngine` in order to use
expert internal apis, such as using Lucene directly to find index term
statistics. These documents prepare the way to remove both native
scripts and IndexLookup.
The example java code is actually compiled and tested under a new gradle
subproject for example plugins. This change does not yet breakup
jvm-example into the new examples dir, which should be done separately.

Specifying s3 access and secret keys inside repository settings are not
secure. However, until there is a way to dynamically update secure
settings, this is the only way to dynamically add repositories with
credentials that are not known at node startup time. This commit adds
back `access_key` and `secret_key` s3 repository settings, but protects
it with a required system property `allow_insecure_settings`.
This PR introduces a subproject in test/fixtures that contains a Vagrantfile used for standing up a
KRB5 KDC (Kerberos). The PR also includes helper scripts for provisioning principals, a few
changes to the HDFS Fixture to allow it to interface with the KDC, as well as a new suite of
integration tests for the HDFS Repository plugin.
The HDFS Repository plugin senses if the local environment can support the HDFS Fixture
(Windows is generally a restricted environment). If it can use the regular fixture, it then tests if
Vagrant is installed with a compatible version to determine if the secure test fixtures should be
enabled. If the secure tests are enabled, then we create a Kerberos KDC fixture, tasks for adding
the required principals, and an HDFS fixture configured for security. A new integration test task is
also configured to use the KDC and secure HDFS fixture and to run a testing suite that uses
authentication. At the end of the secure integration test the fixtures are torn down.
Adds a new "icu_collation" field type that exposes lucene's
ICUCollationDocValuesField. ICUCollationDocValuesField is the replacement
for ICUCollationKeyFilter which has been deprecated since Lucene 5.
This changes the way we register pre-configured token filters so that
plugins can declare them and starts to move all of the pre-configured
token filters out of core. It doesn't finish the job because doing
so would make the change unreviewably large. So this PR includes
a shim that keeps the "old" way of registering pre-configured token
filters around.
The Lowercase token filter is special because there is a "special"
interaction between it and the lowercase tokenizer. I'm not sure
exactly what to do about it so for now I'm leaving it alone with
the intent of figuring out what to do with it in a followup.
This also renames these pre-configured token filters from
"pre-built" to "pre-configured" because that seemed like a more
descriptive name.
This is a part of #23658
Changes the scope of the AllocationService dependency injection hack so that it is at least contained to the AllocationService and does not leak into the Discovery world.
Added missing permissions required for authenticating with Kerberos to HDFS. Also implemented
code to support authentication in the form of using a Kerberos keytab file. In order to support
HDFS authentication, users must install a Kerberos keytab file on each node and transfer it to the
configuration directory. When a user specifies a Kerberos principal in the repository settings the
plugin automatically enables security for Hadoop and begins the login process. There will be a
separate PR and commit for the testing infrastructure to support these changes.
This commit cleans up some cases where a list or map was being
constructed, and then an existing collection was copied into the new
collection. The clean is to instead use an appropriate constructor to
directly copy the existing collection in during collection
construction. The advantage of this is that the new collection is sized
appropriately.

Separates cluster state publishing from applying cluster states:
- ClusterService is split into two classes MasterService and ClusterApplierService. MasterService has the responsibility to calculate cluster state updates for actions that want to change the cluster state (create index, update shard routing table, etc.). ClusterApplierService has the responsibility to apply cluster states that have been successfully published and invokes the cluster state appliers and listeners.
- ClusterApplierService keeps track of the last applied state, but MasterService is stateless and uses the last cluster state that is provided by the discovery module to calculate the next prospective state. The ClusterService class is still kept around, which now just delegates actions to ClusterApplierService and MasterService.
- The discovery implementation is now responsible for managing the last cluster state that is used by the consensus layer and the master service. It also exposes the initial cluster state which is used by the ClusterApplierService. The discovery implementation is also responsible for adding the right cluster-level blocks to the initial state.
- NoneDiscovery has been renamed to TribeDiscovery as it is exclusively used by TribeService. It adds the tribe blocks to the initial state.
- ZenDiscovery is synchronized on state changes to the last cluster state that is used by the consensus layer and the master service, and does not submit cluster state update tasks anymore to make changes to the disco state (except when becoming master).
Control flow for cluster state updates is now as follows:
- State updates are sent to MasterService
- MasterService gets the latest committed cluster state from the discovery implementation and calculates the next cluster state to publish
- MasterService submits the new prospective cluster state to the discovery implementation for publishing
- Discovery implementation publishes cluster states to all nodes and, once the state is committed, asks the ClusterApplierService to apply the newly committed state.
- ClusterApplierService applies state to local node.
The tribe service can take a while to initialize, depending on how many cluster it needs to connect to. This change moves writing the ports file used by tests to before the tribe service is started.
Most of these settings should always be pulled from the repository
settings. A couple were leftover that should be moved to client
settings. The path style access setting should be removed altogether.
This commit adds deprecations for all of these existing settings, as
well as adding new client specific settings for max retries and
throttling.

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 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`.

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
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.
The S3 repostiory has many levels of settings it looks at to create a
repository, and these settings were read at repository creation time.
This meant secure settings like access and secret keys had to be
available after node construction. This change makes setting loading for
every except repository level settings eager, so that secure settings
can be stashed, and the keystore can once again be closed after
bootstrapping the node is complete.
This commit removes passing the repository metadata object through to
s3 client creation. It is not needed, and in fact in tests was confusing
because you could create the metadata but have it contain different
settings than were passed in as repository settings.
This commit removes the "legacy" feature of secure settings, which setup
a parallel setting that was a fallback in the insecure
elasticsearch.yml. This was previously used to allow the new secure
setting name to be that of the old setting name, but is now not in use
due to other refactorings. It is much cleaner to just have all secure
settings use new setting names. If in the future we want to reuse the
previous setting name, once support for the insecure settings have been
removed, we can then rename the secure setting. This also adds a test
for the behavior.
This change adds secure settings for access/secret keys and proxy
username/password to ec2 discovery. It adds the new settings with the
prefix `discovery.ec2`, copies other relevant ec2 client settings to the
same prefix, and deprecates all other settings (`cloud.aws.*` and
`cloud.aws.ec2.*`). Note that this is simpler than the client configs
in repository-s3 because discovery is only initialized once for the
entire node, so there is no reason to complicate the configuration with
the ability to have multiple sets of client settings.

Currently, both the Amazon S3 client provides a retry mechanism, and the
S3 blob store also attempts retries for failed read/write requests.
Both retry mechanisms are controlled by the
`repositories.s3.max_retries` setting. However, the S3 blob store retry
mechanism is unnecessary because the Amazon S3 client provided by the
Amazon SDK already handles retries (with exponential backoff) based on
the provided max retry configuration setting (defaults to 3) as long as
the request is retryable. Hence, this commit removes the unneeded retry
logic in the S3 blob store and the S3OutputStream.
Closes#22845
This commit puts all the classes in the repository-s3 plugin into a
single package. In addition to simplifying the plugin, it will make it
easier to test as things that should be package private will not be
difficult to use inside tests alone.

Users can define the number of retries they wish by setting `cloud.azure.storage.xxx.max_retries` where `xxx` is the azure named account.

Previously, the Azure blob store would depend on a 404 StorageException
coming back from Azure if trying to open an input stream to a
non-existent blob. This works for Azure repositories which access a
primary location path. For those configured to access a secondary
location path, the Azure SDK keeps trying for a long while before
returning a 404 StorageException, causing potential delays in the
snapshot APIs. This commit makes an initial check if the blob exists in
Azure and returns immediately with a NoSuchFileException, instead of
trying to open the input stream to the blob.

This commit adds a convenience method for simultaneously asserting
settings deprecations and other warnings and fixes some tests where
setting deprecations and general warnings were present.
The warning header used by Elasticsearch for delivering deprecation
warnings has a specific format (RFC 7234, section 5.5). The format
specifies that the warning header should be of the form
warn-code warn-agent warn-text [warn-date]
Here, the warn-code is a three-digit code which communicates various
meanings. The warn-agent is a string used to identify the source of the
warning (either a host:port combination, or some other identifier). The
warn-text is quoted string which conveys the semantic meaning of the
warning. The warn-date is an optional quoted date that can be in a few
different formats.
This commit corrects the warning header within Elasticsearch to follow
this specification. We use the warn-code 299 which means a
"miscellaneous persistent warning." For the warn-agent, we use the
version of Elasticsearch that produced the warning. The warn-text is
unchanged from what we deliver today, but is wrapped in quotes as
specified (this is important as a problem that exists today is that
multiple warnings can not be split by comma to obtain the individual
warnings as the warnings might themselves contain commas). For the
warn-date, we use the RFC 1123 format.

Load the geoip database the first time a pipeline gets created that has a geoip processor.
This saves memory (measured ~150MB for the city db) in cases when the plugin is installed, but not used.
This is fallout from #23297. That commit wrapped
`InstanceProfileCredentialsProvider` to ensure that the `getCredentials`
and `refresh` methods had privileged access. However, it looks like
there was a test ensuring that `buildCredentials` returned the correct
clazz type. This commit adjusts that test to check that the correct
wrapper is returned.
The test setup for hdfs is a little complicated for windows, needing to
check if the hdfs fixture can be run at all. This was unfortunately not
updated when the integ tests were reorganized into separate runner and
cluster setups.
This commit fixes an issue that was missed in #22534.
`AWSCredentialsProvider.getCredentials()` appears to potentially open a
socket connect. This operation needed to be wrapped in `doPrivileged()`.
This should fix issue #23271.
Gradle's finalizedBy on tasks only ensures one task runs after another,
but not immediately after. This is problematic for our integration tests
since it allows multiple project's integ test clusters to be
simultaneously. While this has not been a problem thus far (gradle 2.13
happened to keep the finalizedBy tasks close enough that no clusters
were running in parallel), with gradle 3.3 the task graph generation has
changed, and numerous clusters may be running simultaneously, causing
memory pressure, and thus generally slower tests, or even failure if the
system has a limited amount of memory (eg in a vagrant host).
This commit reworks how integ tests are configured. It adds an
`integTestCluster` extension to gradle which is equivalent to the current
`integTest.cluster` and moves the rest test runner task to
`integTestRunner`. The `integTest` task is then just a dummy task,
which depends on the cluster runner task, as well as the cluster stop
task. This means running `integTest` in one project will both run the
rest tests, and shut down the cluster, before running `integTest` in
another project.
Today we have multiple ways to define settings when a user needs to create a repository:

* Remove in 6.x (this PR)

This commit adds the elasticsearch LICENSE.txt to all plugins that
released with elasticsearch, as well as a generated NOTICE.txt specific
to the dependencies of each plugin.
We have a bunch of interfaces that have only a single implementation
for 6 years now. These interfaces are pretty useless from a SW development
perspective and only add unnecessary abstractions. They also require
lots of casting in many places where we expect that there is only one
concrete implementation. This change removes the interfaces, makes
all of the classes final and removes the duplicate `foo` `getFoo` accessors
in favor of `getFoo` from these classes.
This is related to #22116. This commit adds calls that require

- java.net.Socket#connect(java.net.SocketAddress)

- java.nio.channels.SocketChannel#connect(java.net.SocketAddress)
Secure settings from the elasticsearch keystore were not yet validated.
This changed improves support in Settings so that secure settings more
seamlessly blend in with normal settings, allowing the existing settings
validation to work. Note that the setting names are still not validated
(yet) when using the elasticsearc-keystore tool.
As part of #22116 we are going to forbid usage of api
java.net.URL#openStream(). However in a number of places across the
we use this method to read files from the local filesystem. This commit
introduces a helper method openFileURLStream(URL url) to read files
from URLs. It does specific validation to only ensure that file:/
urls are read.
Additionlly, this commit removes unneeded method
FileSystemUtil.newBufferedReader(URL, Charset). This method used the
openStream () method which will soon be forbidden. Instead we use the
Files.newBufferedReader(Path, Charset).
This is related to #22116. Core no longer needs `SocketPermission`
`connect`.
This permission is relegated to these modules/plugins:

- discovery-azure-classic plugin
- discovery-ec2 plugin
- discovery-gce plugin
- repository-azure plugin
- repository-gcs plugin
- repository-hdfs plugin

- mocksocket jar
- rest client
- httpcore-nio jar

See https://github.com/elastic/elasticsearch/pull/22079#issuecomment-277035357

This change adds a strict mode for xcontent parsing on the rest layer. The strict mode will be off by default for 5.x and in a separate commit will be enabled by default for 6.0. The strict mode, which can be enabled by setting `http.content_type.required: true` in 5.x, will require that all incoming rest requests have a valid and supported content type header before the request is dispatched. In the non-strict mode, the Content-Type header will be inspected and if it is not present or not valid, we will continue with auto detection of content like we have done previously.
The content type header is parsed to the matching XContentType value with the only exception being for plain text requests. This value is then passed on with the content bytes so that we can reduce the number of places where we need to auto-detect the content type.
As part of this, many transport requests and builders were updated to provide methods that
accepted the XContentType along with the bytes and the methods that would rely on auto-detection have been deprecated.
In the non-strict mode, deprecation warnings are issued whenever a request with body doesn't provide the Content-Type header.

For example if you defined a tag `my-elasticsearch-host` in ec2 and set it to `myhostname1.mydomain.com`, then
setting `host_type: tag:my-elasticsearch-host` will tell Discovery Ec2 plugin to read the host name from the
`my-elasticsearch-host` tag. In this case, it will be resolved to `myhostname1.mydomain.com`.

This changes build files so that building Elasticsearch works with both Gradle 2.13 as well as higher versions of Gradle (tested 2.14 and 3.3), enabling a smooth transition from Gradle 2.13 to 3.x.
In some cases (apparently with outlook files), mime4j library is needed.

This commit replaces specialized functional interfaces in various

Additionally, this commit introduces a single static method to check that
the current code has permission. This avoids all the duplicated access
blocks that exist currently.
* Upgrade to Lucene 6.4.0
`ValueSource`s are now converted to `DoubleValueSource`s using the Lucene adapter made for the migration to the new API in 6.4.0.
There are presently 7 ctor args used in any rest handlers:
* `Settings`: Every handler uses it to initialize a logger and
some other strange things.
* `RestController`: Every handler registers itself with it.
* `ClusterSettings`: Used by `RestClusterGetSettingsAction` to
render the default values for cluster settings.
* `IndexScopedSettings`: Used by `RestGetSettingsAction` to get
the default values for index settings.
* `SettingsFilter`: Used by a few handlers to filter returned
settings so we don't expose stuff like passwords.
* `IndexNameExpressionResolver`: Used by `_cat/indices` to
filter the list of indices.
* `Supplier<DiscoveryNodes>`: Used to fill enrich the response
by handlers that list tasks.
We probably want to reduce these arguments over time but
switching construction away from guice gives us tighter
control over the list of available arguments.
These parameters are passed to plugins using
`ActionPlugin#initRestHandlers` which is expected to build and
return that handlers immediately. This felt simpler than
returning an reference to the ctors given all the different
possible args.
Breaks java plugins by moving rest handlers off of guice.
* S3 repository: Deprecate specifying credentials through env vars and sys props
This is a follow up to #22479, where storing credentials secure way was
added.
This commit fixes an issue with deprecation logging for lenient
booleans. The underlying issue is that adding deprecation logging for
lenient booleans added a static deprecation logger to the Settings
class. However, the Settings class is initialized very early and in CLI
tools can be initialized before logging is initialized. This leads to
status logger error messages. Additionally, the deprecation logging for
a lot of the settings does not provide useful context (for example, in
the token filter factories, the deprecation logging only produces the
name of the setting, but gives no context which token filter factory it
comes from). This commit addresses both of these issues by changing the
call sites to push a deprecation logger through to the lenient boolean
parsing.

Before, the default chunk size for Azure repositories was
-1 bytes, which meant that if the chunk_size was not set on

the BlobStoreRepository's PartSliceStream does not know
how to process negative chunk sizes).

* Settings: Make s3 repository sensitive settings use secure settings

it also moves the main methods for the keystore wrapper into a
SecureSettings interface, in order to allow settings prefixing to work.
Affix settings are useful to namespace a certain setting. Yet, affix settings

As the translog evolves towards a full operations log as part of the
sequence numbers push, there is a need for the translog to be able to
represent operations for which a sequence number was assigned, but the
operation did not mutate the index. Examples of how this can arise are
operations that fail after the sequence number is assigned, and gaps in
this history that arise when an operation is assigned a sequence number
but the operation never completed (e.g., a node crash). It is important
that these operations appear in the history so that they can be
replicated and replayed during recovery as otherwise the history will be
incomplete and local checkpoints will not be able to advance. This
commit introduces a no-op to the translog to set the stage for these
efforts.

The `UnicastZenPing` shows it's age and is the result of many small changes. The current state of affairs is confusing and is hard to reason about. This PR cleans it up (while following the same original intentions). Highlights of the changes are:
1) Clear 3 round flow - no interleaving of scheduling.
2) The previous implementation did a best effort attempt to wait for ongoing pings to be sent and completed. The pings were guaranteed to complete because each used the total ping duration as a timeout. This did make it hard to reason about the total ping duration and the flow of the code. All of this is removed now and ping should just complete within the given duration or not be counted (note that it was very handy for testing, but I move the needed sync logic to the test).
3) Because of (2) the pinging scheduling changed a bit, to give a chance for the last round to complete. We now ping at the beginning, 1/3 and 2/3 of the duration.
4) To offset for (3) a bit, incoming ping requests are now added to on going ping collections.
5) UnicastZenPing never establishes full blown connections (but does reuse them if there). Relates to #22120
6) Discovery host providers are only used once per pinging round. Closes#21739
7) Usage of the ability to open a connection without connecting to a node ( #22194 ) and shorter connection timeouts helps with connections piling up. Closes#19370
8) Beefed up testing and sped them up.
9) removed light profile from production code

`StreamInput#readNamedWriteable`: on startup components register

Right now the parsers take a context object they use to help with
the parsing but I hope to be able to eliminate the need for this
context as most what it is used for at this point is to move
around parser registries which should be replaced by this method
eventually. I make no effort to do so in this PR because it is
big enough already. This is meant to the a start down a road that
allows us to remove classes like `QueryParseContext`,
`AggregatorParsers`, `IndicesQueriesRegistry`, and
`ParseFieldRegistry`.
The goal here is to reduce the amount of plumbing required to
allow parsing pluggable things. With this you don't have to pass
registries all over the place. Instead you must pass a super
registry to fewer places and use it to wrap the reader. This is
the same tradeoff that we use for NamedWriteable and it allows
much, much simpler binary serialization. We think we want that
same thing for xcontent serialization.
The only parsing actually converted to this method is parsing
`ScoreFunctions` inside of `FunctionScoreQuery`. I chose this
because it is relatively self contained.
We are currenlty checking that no deprecation warnings are emitted in our query tests. That can be moved to ESTestCase (disabled in ESIntegTestCase) as it allows us to easily catch where our tests use deprecated features and assert on the expected warnings.
With this commit, we introduce a cache to the geoip ingest processor.
The cache is enabled by default and caches the 1000 most recent items.
The cache size is controlled by the setting `ingest.geoip.cache_size`.
Closes#22074
In some cases, it might happen that the `_all` field gets a field type that is
not totally configured, and in particular lacks analyzers. This is due to the
fact that `AllFieldMapper.TypeParser.getDefault` uses `Defaults.FIELD_TYPE` as
a default field type, which does not have any analyzers configured since it
does not know about the default analyzers.
While I was fixing a documentation issue (#22007), I looked at the code and discovered that we actually never read what the user entered as a `readonly` parameter when he creates an azure repository.
So if someone sends:
```
PUT _snapshot/my_backup4
{
"type": "azure",
"settings": {
"account": "my_account2",
"location_mode": "primary_only",
"readonly": true
}
}
```
The repository is not actually defined as `readonly`.
It's caused by the fact we are always overwriting `readonly`setting based on `location_mode`.
If a user sets it to `primary_only`, `readonly` is forced to `false`.
If a user sets it to `primary_then_secondary`, `readonly` is forced to `false`.
If a user sets it to `secondary_only`, `readonly` is forced to `false`.
Note that with this change, a user can force a `secondary_only` repository to `readonly: false` which will lead him to an error later on when we check the repository as per definition in Azure, a secondary repository is not writable.
Another option could have been to detect this mismatch and throw an exception in that case. Note sure it is worth writing more code though.
Closes#22053.
Since the removal of local discovery of #https://github.com/elastic/elasticsearch/pull/20960 we rely on minimum master nodes to be set in our test cluster. The settings is automatically managed by the cluster (by default) but current management doesn't work with concurrent single node async starting. On the other hand, with `MockZenPing` and the `discovery.initial_state_timeout` set to `0s` node starting and joining is very fast making async starting an unneeded complexity. Test that still need async starting could, in theory, still do so themselves via background threads.
Note that this change also removes the usage of `INITIAL_STATE_TIMEOUT_SETTINGS` as the starting of nodes is done concurrently (but building them is sequential)
For the record, I also had to remove the geo-hash cell and geo-distance range
queries to make the code compile. These queries already throw an exception in
all cases with 5.x indices, so that does not hurt any more.
I also had to rename all 2.x bwc indices from `index-${version}` to
`unsupported-${version}` to make `OldIndexBackwardCompatibilityIT`
happy.
Set lucene version to 6.4.0-snapshot-ec38570 and update all the sha1s/license
Fix invalid combo after upgrade in query_string query. split_on_whitespace=false is disallowed if auto_generate_phrase_queries=true
Adapt the expectations of some tests to the new format of the Lucene explain output
Lucene 6.2 added index and query support for numeric ranges. This commit adds a new RangeFieldMapper for indexing numeric (int, long, float, double) and date ranges and creating appropriate range and term queries. The design is similar to NumericFieldMapper in that it uses a RangeType enumerator for implementing the logic specific to each type. The following range types are supported by this field mapper: int_range, float_range, long_range, double_range, date_range.
Lucene does not provide a DocValue field specific to RangeField types so the RangeFieldMapper implements a CustomRangeDocValuesField for handling doc value support.
When executing a Range query over a Range field, the RangeQueryBuilder has been enhanced to accept a new relation parameter for defining the type of query as one of: WITHIN, CONTAINS, INTERSECTS. This provides support for finding all ranges that are related to a specific range in a desired way. As with other spatial queries, DISJOINT can be achieved as a MUST_NOT of an INTERSECTS query.
Group, List and Affix settings generate a bogus diff that turns the actual
diff into a string containing a json structure for instance:
```
"action" : {
"search" : {
"remote" : {
"" : "{\"my_remote_cluster\":\"[::1]:60378\"}"
}
}
}
```
which make reading the setting impossible. This happens for instance
if a group or affix setting is rendered via `_cluster/settings?include_defaults=true`
This change fixes the issue as well as several minor issues with affix settings that
where not accepted as valid setting today.
Today we eagerly resolve unicast hosts. This means that if DNS changes,
we will never find the host at the new address. Moreover, a single host
failng to resolve causes startup to abort. This commit introduces lazy
resolution of unicast hosts. If a DNS entry changes, there is an
opportunity for the host to be discovered. Note that under the Java
security manager, there is a default positive cache of infinity for
resolved hosts; this means that if a user does want to operate in an
environment where DNS can change, they must adjust
networkaddress.cache.ttl in their security policy. And if a host fails
to resolve, we warn log the hostname but continue pinging other
configured hosts.
When doing DNS resolutions for unicast hostnames, we wait until the DNS
lookups timeout. This appears to be forty-five seconds on modern JVMs,
and it is not configurable. If we do these serially, the cluster can be
blocked during ping for a lengthy period of time. This commit introduces
doing the DNS lookups in parallel, and adds a user-configurable timeout
for these lookups.
Relates #21630
#20960 removed `LocalDiscovery` and we now use `ZenDiscovery` in all our tests. To keep cluster forming fast, we are using a `MockZenPing` implementation which uses static maps to return instant results making master election fast. Currently, we don't set `minimum_master_nodes` causing the occasional split brain when starting multiple nodes concurrently and their pinging is so fast that it misses the fact that one of the node has elected it self master. To solve this, `InternalTestCluster` is modified to behave like a true cluster and manage and set `minimum_master_nodes` correctly with every change to the number of nodes.
Tests that want to manage the settings themselves can opt out using a new `autoMinMasterNodes` parameter to the `ClusterScope` annotation.
Having `min_master_nodes` set means the started node may need to wait for other nodes to be started as well. To combat this, we set `discovery.initial_state_timeout` to `0` and wait for the cluster to form once all node have been started. Also, because a node may wait and ping while other nodes are started, `MockZenPing` is adapted to wait rather than busy-ping.
