integration tests, as they are no longer needed with
index creation now waiting for shards to be started before
returning from the index creation call (by default, it waits
for the primary of each shard to be started before returning,
which is what ensureYellow() was ensuring anyway).

This commit adds a log message when bootstrap checks are enforced
informing the user that they are enforced because they are bound to an
external network interface. We also log if bootstrap checks are being
enforced but system checks are being ignored.

The unit tests for IndicesClusterStateService currently inject random failures upon shard creation/ routing upate / mapping update etc. This commit makes injecting failures optional so that stronger assertions can be made about the local indices / shard state in case of no failures.
Before returning, index creation now waits for the configured number
of shard copies to be started. In the past, a client would create an
index and then potentially have to check the cluster health to wait
to execute write operations. With the cluster health semantics changing
so that index creation does not cause the cluster health to go RED,
this change enables waiting for the desired number of active shards
to be active before returning from index creation.

For historical reasons, the value associated with Priority.IMMEDIATE is
-1. Yet, with a full-cluster restart required on major version upgrades,
we can reset these values so they are conceptually simpler. This commit
resets the values associated with Priority instances.
Today we have an abstraction Priority for representing
priorities. Ideally, these values are a fixed set of constants with a
well-defined ordering which sounds perfect for an enum. This commit
changes Priority so that it is an enum instead of a class.
In Priority there is a field named values that represents an ordered, by
priority, list of all priorities. Yet, this collection is modifiable and
this collection is exposed via the public API. This means that consumers
can modify this list potentially leading to complete chaos. This commit
modifies this field so that it is unmodifiable, documents that the
returned collection is unmodifiable, and returns total order to the
world. We also punish the bad consumer here by making them make a copy
of the returned collection with which they can do as they please. This
fixes a puzzling test failure which only arises if the two tests
(PrioritizedExecutorsTests#testPriorityQueue and
PriorityTests#testCompareTo run in the same JVM, and run in the right
order).

Also introduced a `Processor.Parameters` class that is holder for several services processors rely on,
the IngestPlugin#getProcessors(...) method has been changed to accept `Processor.Parameters` instead
of each service seperately.
Today we log all loaded modules and installed plugins in a single
line. The number of modules has grown, and when plugins are installed a
single log line containing the loaded modules and plugins is
lengthy. With this commit, we log a single module or plugin per line,
log these in sorted order, and also log if no modules or no plugins were
loaded.

This commit renames the Netty 3 transport module from transport-netty to
transport-netty3. This is to make room for a Netty 4 transport module,
transport-netty4.

Currently custom headers that should be passed through rest requests are
registered by depending on the RestController in guice and calling a
registration method. This change moves that registration to a getter for
plugins, and makes the RestController take the set of headers on
construction.
Invocation counts can be used to help judge the selectivity of individual query components in the context of the entire query. E.g. a query may not look selective when run by itself (matches most of the index), but when run in context of a full search request, is evaluated only rarely due to execution order
Since this is modifying the base timing class, it'll enrich both query and agg profiles (as well as future profile results)
Today `node.mode` and `node.local` serve almost the same purpose, they
are a shortcut for `discovery.type` and `transport.type`. If `node.local: true`
or `node.mode: local` is set elasticsearch will start in _local_ mode which means
only nodes within the same JVM are discovered and a non-network based transport
is used. The _local_ mode it only really used in tests or if nodes are embedded.
For both, embedding and tests explicit configuration via `discovery.type` and `transport.type`
should be preferred.
This change removes all the usage of these settings and by-default doesn't
configure a default transport implemenation since netty is now a module. Yet, to make
the user expericence flawless, plugins or modules can set a `http.type.default` and
`transport.type.default`. Plugins set this via `PluginService#additionalSettings()`
which enforces _set-once_ which prevents node startup if set multiple times. This means
that our distributions will just startup with netty transport since it's packaged as a
module unless `transport.type` or `http.transport.type` is explicitly set.
This change also found a bunch of bugs since several NamedWriteables were not registered if a
transport client is used. Now that we don't rely on the `node.mode` leniency which is inherited
instead of using explicit settings, `TransportClient` uses `AssertingLocalTransport` which detects these problems since it serializes all messages.
Closes#16234
The Java API supports this while mostly used for tests it can also be useful in
production environments. For instance if something is automated like a settings change
and we execute some health right after it the settings update might have some consequences
like a reroute which hasn't been fully applied since the preconditions are not fulfilled yet.
For instance if not all shards started the settings update is applied but the reroute won't move
currently initializing shards like in the shrink API test. Sure this could be done by waiting for
green before but if the cluster moves shards due to some side-effects waiting for all events is
still useful. I also took the chance to add unittests to Priority.java
Closes#19419
This adds an extra method, registerWithDeprecatedHandler, to register both a normal handler and a deprecated handler at the same time. This helps with renaming methods as opposed to _just_ deprecated methods.
Today we assert that the tmp files are present but if the recovery
was canceled this might not be the case while still a valid state.
This chance only throws the AssertionError if the recovery is still active.
This moves all netty related code into modules/transport-netty the module is build as a zip file as well as a JAR to serve as a dependency for transport client. For the time being this is required otherwise we have no network based impl. for transport client users. This might be subject to change given that we move forward http client.
* Clean up the generics around significant terms aggregation results
* Reduce code duplicated between `SignificantLongTerms` and
`SignificantStringTerms` by creating `InternalMappedSignificantTerms`
and moving common things there where possible.
* Migrate to `NamedWriteable`
* Line length fixes while I was there
This commit removes support for properties syntax and config files:
- removed support for elasticsearch.properties
- removed support for logging.properties
- removed support for properties content detection in REST APIs
- removed support for properties content detection in Java API

Some tests still start http implicitly or miss configuring the transport clients correctly.
This commit fixes all remaining tests and adds a depdenceny to `transport-netty` from
`qa/smoke-test-http` and `modules/reindex` since they need an http server running on the nodes.
This also moves all required permissions for netty into it's module and out of core.
If a nested, has_child or has_parent query's inner query gets rewritten then the InnerHitBuilder should use that rewritten form too, otherwise this can cause exceptions in a later phase.
Also fixes a bug that HasChildQueryBuilder's rewrite method overwrites max_children with min_children value.
Closes#19353
That exception is currently serialized as its current base class IllegalStateException which confuses code supposed to deal with the stepping down of a master. This is an important exception and we should be able to serialize it correctly. This commit fixes it by moving the exception to inherit from ElasticsearchException and properly register it.
As a bonus I adapted CapturingTransport to properly simulate serialized exceptions.
