`Node#close` is pretty hard to rely on today:
- it might swallow exceptions
- it waits for 10 seconds for threads to terminate but doesn't signal anything
if threads are still not terminated after 10 seconds
This commit makes `IOException`s propagated and splits `Node#close` into
`Node#close` and `Node#awaitClose` so that the decision what to do if a node
takes too long to close can be done on top of `Node#close`.
It also adds synchronization to lifecycle transitions to make them atomic. I
don't think it is a source of problems today, but it makes things easier to
reason about.
This commit removes the settings member variable from Node.
This member made it confusing which settings should actually be looked
at. Now all settings are accessed through the final environment.
* Bundle java in distributions
Setting up a jdk is currently a required external step when installing
elasticsearch. This is particularly problematic for the rpm/deb packages
as installing a jdk in the same package installation command does not
guarantee any order, so must be done in separate steps. Additionally,
JAVA_HOME must be set and often causes problems in selecting a correct
jdk when, for example, the system java is an older unsupported version.
This commit bundles platform specific openjdks into each distribution.
In addition to eliminating the issues above, it also presents future
possible improvements like using jlink to build jdk images only
containing modules that elasticsearch uses.

When extending ESIntegTestCase are run on the same jvm, the static field in
NodeAndClusterIdConverter will throw an AlreadySet exceptions.
overriding the configuration method from Node.configureNodeAndClusterIdStateListener in the MockNode will prevent the listener registration from happening

In order to support JSON log format, a custom pattern layout was used and its configuration is enclosed in ESJsonLayout. Users are free to use their own patterns, but if smooth Beats integration is needed, they should use ESJsonLayout. EvilLoggerTests are left intact to make sure user's custom log patterns work fine.
To populate additional fields node.id and cluster.uuid which are not available at start time,
a cluster state update will have to be received and the values passed to log4j pattern converter.
A ClusterStateObserver.Listener is used to receive only one ClusteStateUpdate. Once update is received the nodeId and clusterUUid are set in a static field in a NodeAndClusterIdConverter.
Following fields are expected in JSON log lines: type, tiemstamp, level, component, cluster.name, node.name, node.id, cluster.uuid, message, stacktrace
see ESJsonLayout.java for more details and field descriptions
Docker log4j2 configuration is now almost the same as the one use for ES binary.
The only difference is that docker is using console appenders, whereas ES is using file appenders.

This commit removes the originalSettings member from Node. It was only
needed to allows test clusters to recreate the node in certain
situations. Instead, the test cluster now keeps track of these settings.
Previously persistent task assignment was checked in the
following situations:
- Persistent tasks are changed
- A node joins or leaves the cluster
- The routing table is changed
- Custom metadata in the cluster state is changed
- A new master node is elected
However, there could be situations when a persistent
task that could not be assigned to a node could become
assignable due to some other change, such as memory
usage on the nodes.
This change adds a timed recheck of persistent task
assignment to account for such situations. The timer
is suspended while checks triggered by cluster state
changes are in-flight to avoid adding burden to an
already busy cluster.
Closes#35792
There are certain BootstrapCheck checks that may need access environment-specific
values. Watcher's EncryptSensitiveDataBootstrapCheck passes in the node's environment
via a constructor to bypass the shortcoming in BootstrapContext. This commit
pulls in the node's environment into BootstrapContext.
Another case is found in #36519, where it is useful to check the state of the
data-path. Since PathUtils.get and Paths.get are forbidden APIs, we rely on
the environment to retrieve references to things like node data paths.
This means that the BootstrapContext will have the same Settings used in the
Environment, which currently differs from the Node's settings.
This commit modifies BigArrays to take a circuit breaker name and
the circuit breaking service. The default instance of BigArrays that
is passed around everywhere always uses the request breaker. At the
network level, we want to be using the inflight request breaker. So this
change will allow that.
Additionally, as this change moves away from a single instance of
BigArrays, the class is modified to not be a Releasable anymore.
Releasing big arrays was always dispatching to the PageCacheRecycler,
so this change makes the PageCacheRecycler the class that needs to be
managed and torn-down.
Finally, this commit closes#31435 be making the serialization of
transport messages use the inflight request breaker. With this change,
we no longer push the global BigArrays instnace to the network level.
This commit implements proper metadata recovery for Zen2.
GatewayService is responsible for the recovery. In Zen1 GatewayService
creates an instance of Gateway, that is used to reach out to other cluster
nodes, get their state and calculate the most up-to-date state based on
versions. After that Gateway performs upgrade and archival of
ClusterSettings and closes bad indices. Then recovered state is passed to GatewayService.GatewayRecoveryListener that mixes up current state
and restored state, removes state not recovered block, creates the
routing table and performs re-routing.
In Zen2 we should perform this kind of logic on cluster startup, except
mixing state (because there is nothing to mix) and opening routing table.
This commit refactors out all `ClusterUpdate` functions in a separate class
`ClusterStateUpdaters`, which is used by `Gateway` and `GatewayService`
in case of Zen1, and by `GatewayMetaState` and `GatewayService` in case of
Zen2.
This commit also switches all integration tests that are already using Zen2 from
InMemoryPersistedState to GatewayMetaState.
Today GatewayMetaState is capable of atomically storing MetaData to
disk. We've also moved fields that are needed to be persisted in Zen2
from ClusterState to ClusterState.MetaData.CoordinationMetaData.
This commit implements PersistedState interface.
version and currentTerm are persisted as a part of Manifest.
GatewayMetaState now implements both ClusterStateApplier and
PersistedState interfaces. We started with two descendants
Zen1GatewayMetaState and Zen2GatewayMetaState, but it turned
out to be not easy to glue it.
GatewayMetaState now constructs previousClusterState (including
MetaData) and previousManifest inside the constructor so that all
PersistedState methods are usable as soon as GatewayMetaState
instance is constructed. Also, loadMetaData is renamed to
getMetaData, because it just returns
previousClusterState.metaData().
Sadly, we don't have access to localNode (obtained from
TransportService in the constructor, so getLastAcceptedState
should be called, after setLocalNode method is invoked.
Currently, when deciding whether to write IndexMetaData to disk,
we're comparing current IndexMetaData version and received
IndexMetaData version. This is not safe in Zen2 if the term has changed.
So updateClusterState now accepts incremental write
method parameter. When it's set to false, we always write
IndexMetaData to disk.
Things that are not covered by GatewayMetaStateTests are covered
by GatewayMetaStatePersistedStateTests.
This commit also adds an option to use GatewayMetaState instead of
InMemoryPersistedState in TestZenDiscovery. However, by default
InMemoryPersistedState is used and only one test in PersistedStateIT
used GatewayMetaState. In order to use it for other tests, proper
state recovery should be implemented.
Elasticsearch node is responsible for storing cluster metadata.
There are 2 types of metadata: global metadata and index metadata.
`GatewayMetaState` implements `ClusterStateApplier` and receives all
`ClusterStateChanged` events and is responsible for storing modified
metadata to disk.
When new `ClusterStateChanged` event is received, `GatewayMetaState`
checks if global metadata has changed and if it's the case writes new
global metadata to disk. After that `GatewayMetaState` checks if index
metadata has changed or there are new indices assigned to this node and
if it's the case writes new index metadata to disk. Atomicity of global
metadata and index metadata writes is ensured by `MetaDataStateFormat`
class.
Unfortunately, there is no atomicity when more than one metadata changes
(global and index, or metadata for two indices). And atomicity is
important for Zen2 correctness.
This commit adds atomicity by adding a notion of manifest file,
represented by `MetaState` class. `MetaState` contains pointers to
current metadata.
More precisely, it stores global state generation as long and map from
`Index` to index metadata generation as long. Atomicity of writes for
manifest file is ensured by `MetaStateFormat` class.
The algorithm of writing changes to the disk would be the following:
1. Write global metadata state file to disk and remember
it's generation.
2. For each new/changed index write state file to disk and remember
it's generation. For each not-changed index use generation from
previous manifest file. If index is removed or this node is no longer
responsible for this index - forget about the index.
3. Create `MetaState` object using previously remembered generations and
write it to disk.
4. Remove old state files for global metadata, indices metadata and
manifest.
Additonally new implementation relies on enhanced `MetaDataStateFormat`
failure semantics, `applyClusterState` throws IOException, whose
descendant `WriteStateException` could be (and should be in Zen2)
explicitly handled.
This commit uses the index settings version so that a follower can
replicate index settings changes as needed from the leader.

With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.
I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler
These files don't *need* `settings` either, but this change is large
enough as is.
Relates to #34488
Changes the default of the `node.name` setting to the hostname of the
machine on which Elasticsearch is running. Previously it was the first 8
characters of the node id. This had the advantage of producing a unique
name even when the node name isn't configured but the disadvantage of
being unrecognizable and not being available until fairly late in the
startup process. Of particular interest is that it isn't available until
after logging is configured. This forces us to use a volatile read
whenever we add the node name to the log.
Using the hostname is available immediately on startup and is generally
recognizable but has the disadvantage of not being unique when run on
machines that don't set their hostname or when multiple elasticsearch
processes are run on the same host. I believe that, taken together, it
is better to default to the hostname.
1. Running multiple copies of Elasticsearch on the same node is a fairly
advanced feature. We do it all the as part of the elasticsearch build
for testing but we make sure to set the node name then.
2. That the node.name defaults to some flavor of "localhost" on an
unconfigured box feels like it isn't going to come up too much in
production. I expect most production deployments to at least set the
hostname.
As a bonus, production deployments need no longer set the node name in
most cases. At least in my experience most folks set it to the hostname
anyway.
In some cases we want to deprecate a setting, and then automatically
upgrade uses of that setting to a replacement setting. This commit adds
infrastructure for this so that we can upgrade settings when recovering
the cluster state, as well as when such settings are dynamically applied
on cluster update settings requests. This commit only focuses on cluster
settings, index settings can build on this infrastructure in a
follow-up.
Change the logging infrastructure to handle when the node name isn't
available in `elasticsearch.yml`. In that case the node name is not
available until long after logging is configured. The biggest change is
that the node name logging no longer fixed at pattern build time.
Instead it is read from a `SetOnce` on every print. If it is unset it is
printed as `unknown` so we have something that fits in the pattern.
On normal startup we don't log anything until the node name is available
so we never see the `unknown`s.
This commit is related to #32517. It allows an "server_name"
attribute on a DiscoveryNode to be propagated to the server using
the TLS SNI extentsion. This functionality is only implemented for
the netty security transport.
This commit introduces the formal notion of a private setting. This
enables us to register some settings that we had previously not
registered as fully-fledged settings to avoid them being exposed via
APIs such as the create index API. For example, we had hacks in the
codebase to allow index.version.created to be passed around inside of
settings objects, but was not registered as a setting so that if a user
tried to use the setting on any API then they would get an
exception. This prevented users from setting index.version.created on
index creation, or updating it via the index settings API. By
introducing private settings, we can continue to reject these attempts,
yet now we can represent these settings as actual settings. In this
change, we register index.version.created as an actual setting. We do
not cutover all settings that we had been treating as private in this
pull request, it is already quite large due to moving some tests around
to account for the fact that some tests need to be able to set the
index.version.created. This can be done in a follow-up change.
Today we support a static list of seed hosts in core Elasticsearch, and allow a
dynamic list of seed hosts to be provided via a file using the `discovery-file`
plugin. In fact the ability to provide a dynamic list of seed hosts is
increasingly useful, so this change moves this functionality to core
Elasticsearch to avoid the need for a plugin.
Furthermore, in order to start up nodes in integration tests we currently
assign a known port to each node before startup, which unfortunately sometimes
fails if another process grabs the selected port in the meantime. By moving the
`discovery-file` functionality into the core product we can use it to avoid
this race.
This change also moves the expected path to the file from
`$ES_PATH_CONF/discovery-file/unicast_hosts.txt` to
`$ES_PATH_CONF/unicast_hosts.txt`. An example of this file is not included in
distributions.
For BWC purposes the plugin still exists, but does nothing more than create the
example file in the old location, and issue a warning when it is used. We also
continue to support the old location for the file, but warn about its
deprecation.

Scripting: Fix painless compiler loader to know about context classes (#32385)
First, some background: we have 15 different methods to get a logger in
Elasticsearch but they can be broken down into three broad categories
based on what information is provided when building the logger.
Just a class like:
```
private static final Logger logger = ESLoggerFactory.getLogger(ActionModule.class);
```
or:
```
protected final Logger logger = Loggers.getLogger(getClass());
```
The class and settings:
```
this.logger = Loggers.getLogger(getClass(), settings);
```
Or more information like:
```
Loggers.getLogger("index.store.deletes", settings, shardId)
```
The goal of the "class and settings" variant is to attach the node name
to the logger. Because we don't always have the settings available, we
often use the "just a class" variant and get loggers without node names
attached. There isn't any real consistency here. Some loggers get the
node name because it is convenient and some do not.
This change makes the node name available to all loggers all the time.
Almost. There are some caveats are testing that I'll get to. But in
*production* code the node name is node available to all loggers. This
means we can stop using the "class and settings" variants to fetch
loggers which was the real goal here, but a pleasant side effect is that
the ndoe name is now consitent on every log line and optional by editing
the logging pattern. This is all powered by setting the node name
statically on a logging formatter very early in initialization.
Now to tests: tests can't set the node name statically because
subclasses of `ESIntegTestCase` run many nodes in the same jvm, even in
the same class loader. Also, lots of tests don't run with a real node so
they don't *have* a node name at all. To support multiple nodes in the
same JVM tests suss out the node name from the thread name which works
surprisingly well and easy to test in a nice way. For those threads
that are not part of an `ESIntegTestCase` node we stick whatever useful
information we can get form the thread name in the place of the node
name. This allows us to keep the logger format consistent.

Today we allow plugins to add index store implementations yet we are not
doing this in our new way of managing plugins as pull versus push. That
is, today we still allow plugins to push index store providers via an on
index module call where they can turn around and add an index
store. Aside from being inconsistent with how we manage plugins today
where we would look to pull such implementations from plugins at node
creation time, it also means that we do not know at a top-level (for
example, in the indices service) which index stores are available. This
commit addresses this by adding a dedicated plugin type for index store
plugins, removing the index module hook for adding index stores, and by
aggregating these into the top-level of the indices service.

RolloverInfo. This object contains a map containing the aliases

were met, and at what time the rollover took place.
much like the `index.creation_date`, it captures the approximate time
that the index was rolled over to a new one.

When doing a node restart using the test framework, the restarted node does not only use the
settings provided to the original node, but also additional settings provided by plugin extensions,
which does not correspond to the settings that a node would have on a true restart.

This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.
closes#12792
