Use default memory lock setting in testing (#40730)
Today we are running our internal tests with bootstrap.memory_lock
enabled. This is not out default setting, and not the recommended
value. This commit switches to use the default value, which is to not
enable bootstrap.memory_lock.

Alpar Torok 293297ae3d Fix repository-hdfs when no docker and unnecesary fixture
The hdfs-fixture is actually executed in plugin/repository-hdfs as a
dependency. The fixture is not needed and actually causes a failure

Alpar Torok d791e08932 Test fixtures krb5 (#40297)
Replaces the vagrant based kerberos fixtures with docker based test fixtures plugin.
The configuration is now entirely static on the docker side and no longer driven by Gradle,
also two different services are being configured since there are two different consumers of the fixture that can run in parallel and require different configurations.

Get node ID from nodes info in REST tests (#40052) (#40532)
We discussed recently that the cluster state API should be considered
"internal" and therefore our usual cast-iron stability guarantees do not hold
for this API.

However, there are a good number of REST tests that try to identify the master
node. Today they call `GET /_cluster/state` API and extract the master node ID
from the response. In fact many of these tests just want an arbitary node ID
(or perhaps a data node ID) so an alternative is to call `GET _nodes` or `GET
_nodes/data:true` and obtain a node ID from the keys of the `nodes` map in the
response.

This change adds the ability for YAML-based REST tests to extract an arbitrary
key from a map so that they can obtain a node ID from the nodes info API
instead of using the master node ID from the cluster state API.

Relates #40047.

Yannick Welsch 64b31f44af No mapper service and index caches for replicated closed indices (#40423)
Replicated closed indices can't be indexed into or searched, and therefore don't need a shard with
full indexing and search capabilities allocated. We can save on a lot of heap memory for those
indices by not allocating a mapper service and caching infrastructure (which preallocates a constant
amount per instance). Before this change, a 1GB ES instance could host 250 replicated closed
metricbeat indices (each index with one shard). After this change, the same instance can host 7300
replicated closed metricbeat instances (not that this would be a recommended configuration). Most
of the remaining memory is in the cluster state and the IndexSettings object.

Yannick Welsch 8f7c5732f1 Use default discovery implementation for single-node discovery (#40036)
Switches "discovery.type: single-node" from using a separate implementation for single-node discovery to using the existing standard discovery implementation, with two small adaptions:

-  auto-bootstrapping, but requiring initial_master_nodes not to be set.
- not actively pinging other nodes using the Peerfinder
- not allowing other nodes to join its single-node cluster (if they have e.g. been set up using regular discovery and connect to the single-disco node).

Move outbound message handling to OutboundHandler (#40336)
Currently there are some components of message serializer and sending

Henning Andersen bf444b9f02 Store Pending Deletions Fix (#40345)
FilterDirectory.getPendingDeletions does not delegate, fixed
temporarily by overriding in StoreDirectory.

This in turn caused duplicate file name use after a trimUnsafeCommits
had been done, since a new IndexWriter would not consider the pending
deletes in IndexFileDeleter. This should only happen on windows (AFAIK).

Reenabled doing index updates for all tests using
IndexShardTests.indexOnReplicaWithGaps (which could fail due to above
when using mocked WindowsFS).

Added getPendingDeletions delegation to all elasticsearch
FilterDirectory subclasses that were not trivial test-only overrides to
minimize the risk of hitting this issue in another case.

Remove transport name from tcp channel (#40074)
Currently, we maintain a transport name ("mock-nio", "nio", "netty")
that is passed to a `TcpTransportChannel` when a request is received.
The value of this name is to associate with the task when we register a
task with the task manager. However, it is only possible to run ES with
one transport, so having an implementation specific name is unnecessary.
This commit removes the name and replaces it with the generic
"transport".

David Turner a323132503 Create retention leases file during recovery (#39359)
Today we load the shard history retention leases from disk whenever opening the
engine, and treat a missing file as an empty set of leases. However in some
cases this is inappropriate: we might be restoring from a snapshot (if the
target index already exists then there may be leases on disk) or
force-allocating a stale primary, and in neither case does it make sense to
restore the retention leases from disk.

With this change we write an empty retention leases file during recovery,
except for the following cases:

- During peer recovery the on-disk leases may be accurate and could be needed
  if the recovery target is made into a primary.

- During recovery from an existing store, as long as we are not
  force-allocating a stale primary.

Stop returning cluster state size by default (#40016)
Computing the compressed size of the cluster state on every invocation
of cluster:monitor/state action is expensive, and the value of this
field is dubious anyway. Therefore we want to remove computing this
field. As a first step, we stop computing and return this field by
default. To avoid breaking users, we will give them a system property to
use to tide them over until the next major release when we will actually
remove this field. This comes with a deprecation warning too, and the
backport to the appropriate minor will also include a note in the
migration guide. There will be a follow-up to remove this field in the
next major version.

David Turner 049970af3e Only connect to new nodes on new cluster state (#39629)
Today, when applying new cluster state we attempt to connect to all of its
nodes as a blocking part of the application process. This is the right thing to
do with new nodes, and is a no-op on any already-connected nodes, but is
questionable on known nodes from which we are currently disconnected: there is
a risk that we are partitioned from these nodes so that any attempt to connect
to them will hang until it times out. This can dramatically slow down the
application of new cluster states which hinders the recovery of the cluster
during certain kinds of partition.

If nodes are disconnected from the master then it is likely that they are to be
removed as part of a subsequent cluster state update, so there's no need to try
and reconnect to them like this. Moreover there is no need to attempt to
reconnect to disconnected nodes as part of the cluster state application
process, because we periodically try and reconnect to any disconnected nodes,
and handle their disconnectedness reasonably gracefully in the meantime.

This commit alters this behaviour to avoid reconnecting to known nodes during
cluster state application.

Resolves #29025.

Nhat Nguyen 1fe7cb594f Don’t ack if unable to remove failing replica (#39584)
Today when a replicated write operation fails to execute on a replica,
the primary will reach out to the master to fail that replica (and mark
it stale). We then won't ack that request until the master removes the
failing replica; otherwise, we will lose the acked operation if the
failed replica is still in the in-sync set. However, if a node with the
primary is shutting down, we might ack such request even though we are
unable to send a shard-failure request to the master. This happens
because we ignore NodeClosedException which is triggered when the
ClusterService is being closed.

David Turner 295e39a8c8 Drop node if asymmetrically partitioned from master (#39598)
When a node is joining the cluster we ensure that it can send requests to the
master _at that time_. If it joins the cluster and _then_ loses the ability to
send requests to the master then it should be removed from the cluster. Today
this is not the case: the master can still receive responses to its follower
checks, and receives acknowledgements to cluster state publications, so has no
reason to remove the node.

This commit changes the handling of follower checks so that they fail if they
come from a master that the other node was following but which it now believes
to have failed.

Backport support for replicating closed indices to 7.x (#39506)(#39499)
Backport support for replicating closed indices (#39499)
    
    Before this change, closed indexes were simply not replicated. It was therefore
    possible to close an index and then decommission a data node without knowing
    that this data node contained shards of the closed index, potentially leading to
    data loss. Shards of closed indices were not completely taken into account when
    balancing the shards within the cluster, or automatically replicated through shard
    copies, and they were not easily movable from node A to node B using APIs like
    Cluster Reroute without being fully reopened and closed again.
    
    This commit changes the logic executed when closing an index, so that its shards
    are not just removed and forgotten but are instead reinitialized and reallocated on
    data nodes using an engine implementation which does not allow searching or
     indexing, which has a low memory overhead (compared with searchable/indexable
    opened shards) and which allows shards to be recovered from peer or promoted
    as primaries when needed.
    
    This new closing logic is built on top of the new Close Index API introduced in
    6.7.0 (#37359). Some pre-closing sanity checks are executed on the shards before
    closing them, and closing an index on a 8.0 cluster will reinitialize the index shards
    and therefore impact the cluster health.
    
    Some APIs have been adapted to make them work with closed indices:
    - Cluster Health API
    - Cluster Reroute API
    - Cluster Allocation Explain API
    - Recovery API
    - Cat Indices
    - Cat Shards
    - Cat Health

Nhat Nguyen 48219112e3 Do not wait for advancement of checkpoint in recovery (#39006)
With this change, we won't wait for the local checkpoint to advance to
the max_seq_no before starting phase2 of peer-recovery. We also remove
the sequence number range check in peer-recovery. We can safely do these
thanks to Yannick's finding.

The replication group to be used is currently sampled after indexing
into the primary (see `ReplicationOperation` class). This means that
when initiating tracking of a new replica, we have to consider the
following two cases:

- There are operations for which the replication group has not been
sampled yet. As we initiated the new replica as tracking, we know that
those operations will be replicated to the new replica and follow the
typical replication group semantics (e.g. marked as stale when
unavailable).

- There are operations for which the replication group has already been
sampled. These operations will not be sent to the new replica.  However,
we know that those operations are already indexed into Lucene and the
translog on the primary, as the sampling is happening after that. This
means that by taking a snapshot of Lucene or the translog, we will be
getting those ops as well. What we cannot guarantee anymore is that all
ops up to `endingSeqNo` are available in the snapshot (i.e.  also see
comment in `RecoverySourceHandler` saying `We need to wait for all
operations up to the current max to complete, otherwise we can not
guarantee that all operations in the required range will be available
for replaying from the translog of the source.`). This is not needed,
though, as we can no longer guarantee that max seq no == local
checkpoint.

However, we do not listen for changes. This commit adds listeners for
changes to those two settings. Additionally, when those settings change
we now close existing connections and open new ones with the settings
applied.

Fixes #37201.
