* Swithc to jcenter
Jcenter suposedly operates on a CDN.
It should be faster and more reliable.
It's the default in Andorid Studio currently
( it switched from mavenCentral ).
This change is safe because jcenter is a superset of mavenCentral.

Today, the TransportReplicationAction checks the global level blocks and
the index level blocks before routing the operation to the primary, in the
ReroutePhase, and it happens at the very beginning of the transport
replication action execution. For the upcoming rework of the Close Index
API and in order to deal with primary relocation, we'll need to also check
for blocks before executing the operation on the primary (while holding a
permit) but before routing to the new primary.
This pull request change the AsyncPrimaryAction so that it checks for
replication action's blocks before executing the operation locally or before
routing the primary action to the newly primary shard. The check is done
while holding a PrimaryShardReference.

For some time, the PutUser REST API has supported storing a pre-hashed
password for a user. The change adds validation and tests around that
feature so that it can be documented & officially supported.
It also prevents the request from containing both a "password" and a "password_hash".
The way ScoreAccessor implements `compareTo()` is problematic because it doesn't
completely follow the Comparable contract, specificaly symmetry (if x is a
ScoreAccessor and y any Number then x.comparTo(y) works, but y.compareTo(x)
generally does not even compile). Fortunately we don't seem to use the fact that
ScoreAccessor is a Comparable anywhere, so we can simply remove it.
Today the `PeerFinder` probes each address it obtains, identifies the node to
which it just connected, and then returns all such nodes. However, this can
lead to duplicates if a node manages to connect to another node via two
distinct addresses. This causes bootstrapping to fail since
`BootstrapConfiguration#resolve` forbids duplicates.
This change alters the behaviour of the `PeerFinder` to remove duplicates in
this situation.
This adds a `wait_for_completion` flag which allows the user to block
the Stop API until the task has actually moved to a stopped state,
instead of returning immediately. If the flag is set, a `timeout` parameter
can be specified to determine how long (at max) to block the API
call. If unspecified, the timeout is 30s.
If the timeout is exceeded before the job moves to STOPPED, a
timeout exception is thrown. Note: this is just signifying that the API
call itself timed out. The job will remain in STOPPING and evenutally
flip over to STOPPED in the background.
If the user asks the API to block, we move over the the generic
threadpool so that we don't hold up a networking thread.
* Adds HLRC docs for put lifecycle policy
* Adds link to docs in client javadocs
* Fixes checkstyle
* Make the documentation use the right ack response
If shutting down half or more of the master-eligible nodes, their votes must
first be explicitly withdrawn to ensure that the cluster doesn't lose its
quorum. This works via _voting tombstones_, stored in the cluster state, which
tell the reconfigurator to remove nodes from the voting configuration.
This change introduces voting tombstones to the cluster state, together with
transport APIs for adding and removing them, and makes use of these APIs in
`InternalTestCluster` to support tests which remove at least half of the
master-eligible nodes at once (e.g. shrinking from two master-eligible nodes to
one).
* [ILM] Add documentation for error handling in ILM
This adds some initial documentation for error handling and retrying failed
steps for index lifecycle management
AbstractComponent was deprecated in #35140 and is looking like it will be
removed at some point by #34888. Today all it does is provide a logger. This
change removes the usages of AbstractComponent that live solely in the zen2
feature branch to avoid some future merge pain, and replaces it where necessary
with some directly-created loggers.
Implement high level client for migration upgrade API. It should wrap
RestHighLevelClient and expose high level IndexUpgradeRequest (new),
IndexTaskResponse for submissions with wait_for_completion=false and
BulkByScrollResponse (already used) objects.

This change adds a special caching reader that caches all relevant
values for a range query to rewrite correctly in a can_match phase
without actually opening the underlying directory reader. This
allows frozen indices to be filtered with can_match and in-turn
searched with wildcards in a efficient way since it allows us to
exclude shards that won't match based on their date-ranges without
opening their directory readers.
Relates to #34352
Depends on #34357
* DISCOVERY: 0s Initial State Timeout in Tests
* Don't wait for initial state even with a single node, otherwise the loop writing the discovery file causes that single node to wait
for its own transport.ports file for 30s.
* Closes#35456
The ParsedReverseNested implementation should implement the ReverseNested
interface and not the Nested interface. Although this is an empty marker
interface it is confusing and can lead to casting errors. Also adding a test to
check that both ParsedNested and ParsedReverseNested implement the correct
interface.
Closes#35449
The NPE would occur if should_trim_field was overridden to
true and any field value was completely blank. This change
defends against this situation.
Fixes#35462
Some very old ancient versions of Linux do not have /etc/os-release. For
example, old Red Hat-like OS. This commit adds a fallback for handling
pretty name for these OS.
This is a follow up to #35357. That commit failed to register the new
cluster.remote.cluster_name.transport.compress setting with
`ClusterSettings`. This commit fixes that.
Before, moving to a failed step would only change the step info
to be that of the failed step. This means two things.
1. Async Steps would never be triggered to execute
2. If there are inherent problems with the action definition that can
be fixed with a policy update, these changes were not being reflected
by the new execution info.
Changes now
1. Async steps are executed after the move to the failed step in cluster state
2. the lifecycle execution info's phase definition is updated from the current
latest policy definition, even though the index isn't moving to a new phase.
Closes#35397.
Some OS (e.g., Oracle Linux Server 6.9) have a trailing space at the end
of the PRETTY_NAME line in /etc/os-release. This commit addresses this
by accounting for this trailing space when extracting the pretty name.
Implements serialization compatibility between Zen1 and Zen2 transport action, allowing a Zen1 node to join a fully formed Zen2 cluster and vice-versa.
Given a GetTaskRequest the API returns an Optional which is empty in the case of 404s or returns a TaskInfo object if found.
Added Helper methods in RestHighLevelClient for returning empty Optionals when hitting 404s
Today it is unclear that the `storage_class` parameter to an S3 repository only
affects new objects and does not rewrite any existing objects. This commit
clarifies this point.
