Adrien Grand 91fe8d5366 Enforce that bash is used when running `gradle run`.
Using `sh` means we used whatever default the system has, which is `dash` on
Ubuntu, even though our startup script is written for bash (see the shebang).

Jason Tedor 46d75a3552 Fix broken quotes in systemd unit file
The quoting for the ExecStart entry is broken as quotes must wrap an
entire argument, and arguments are separated by spaces. It turns out
that any quoting is unnecessary here, systemd will handle it correctly
either way.

Simon Willnauer 0e3ad522a2 Rewrite search requests on the coordinating nodes (#25814)
This change rewrites search requests on the coordinating node before
we send requests to the individual shards. This will reduce the rewrite load
and object creation for each rewrite on the executing nodes and will fetch
resources only once instead of N times once per shard for queries like `terms`
query with index lookups. (among percolator and geo-shape)

Simon Willnauer 0d0c103451 First increment shard stats before notifing and potentially sending response (#25818)
When we skip a shard we should first increment the skip and successful shard
counters before we notify the super class about a skipped shard which could
send back the result before we increment the stats.

Jason Tedor 0310a6a947 Introduce elasticsearch-env
This commit introduces the elasticsearch-env script. The purpose of this
script is threefold:
 - vastly simplify the various scripts used in Elasticsearch
 - provide a script that can be included in other scripts in the
   Elasticsearch ecosystem (e.g., plugins)
 - correctly establish the environment for all scripts (e.g., so that
   users can run `elasticsearch-keystore` from a package distribution
   without having to worry about setting `CONF_DIR` first, otherwise the
   keystore would be created in the wrong location)

Ryan Ernst cfdfa4705e Bump the min compat version to 5.6.0 (#25805)

compat versions are, similar to how we test the lucene version.

Boaz Leskes 7488877d1a Validate a joining node's version with version of existing cluster nodes (#25808)
When a node tries to join a cluster, it goes through a validation step to make sure the node is compatible with the cluster. Currently we validation that the node can read the cluster state and that it is compatible with the indexes of the cluster. This PR adds validation that the joining node's version is compatible with the versions of existing nodes. Concretely we check that:

1) The node's min compatible version is higher or equal to any node in the cluster (this prevents a too-new node from joining)
2) The node's version is higher or equal to the min compat version of all cluster nodes (this prevents a too old join where, for example, the master is on 5.6, there's another 6.0 node in the cluster and a 5.4 node tries to join).
3) The node's major version is at least as higher as the lowest node in the cluster. This is important as we use the minimum version in the cluster to stop executing bwc code for operations that require multiple nodes. If the nodes are already operating in "new cluster mode", we should prevent nodes from the previous major to join (even if they are wire level compatible). This does mean that if you have a very unlucky partition during the upgrade which partitions all old nodes which are also a minority / data nodes only, the may not be able to re-join the cluster. We feel this edge case risk is well worth the simplification it brings to BWC layers only going one way. This restriction only holds if the cluster state has been recovered (i.e., the cluster has properly formed).

 Also, the node join validation can now selectively fail specific nodes (previously the entire batch was failed). This is an important preparation for a follow up PR where we plan to have a rejected joining node die with dignity.

Simon Willnauer 5e629cfba0 Ensure query resources are fetched asynchronously during rewrite (#25791)
The `QueryRewriteContext` used to provide a client object that can
be used to fetch geo-shapes, terms or documents for percolation. Unfortunately
all client calls used to be blocking calls which can have significant impact on the
rewrite phase since it occupies an entire search thread until the resource is
received. In the case that the index the resource is fetched from isn't on the local
node this can have significant impact on query throughput.

Note: this doesn't fix MLT since it fetches stuff in doQuery which is a different beast. Yet, it is a huge step in the right direction

Jason Tedor 3042b5dc7d Stop exporting HOSTNAME from scripts
Today we explicitly export the HOSTNAME variable from scripts. This is
probably a relic from the days when the scripts were not run on bash but
instead assume a POSIX-compliant shell only where HOSTNAME is not
guaranteed to exist. Yet, bash guarantees that HOSTNAME is set so we do
not need to set it in scripts. This commit removes this legacy.

Jason Tedor 67a4288c9a Remove support for ES_INCLUDE
Today we enable users to customize the environment through the use of
ES_INCLUDE. This made sense for legacy reasons when we did not have
nicities like jvm.options (so dumped JVM options in the default include
script) and somewhat duplicates some of the functionality that we will
need from a dedicated environment script. This commit removes support
for ES_INCLUDE as a first step towards a dedicated include script.

Adrien Grand 55ad318541 Reduce the overhead of timeouts and low-level search cancellation. (#25776)
Setting a timeout or enforcing low-level search cancellation used to make us
wrap the collector and check either the current time or whether the search
task was cancelled for every collected document. This can be significant
overhead on cheap queries that match many documents.

This commit changes the approach to wrap the bulk scorer rather than the
collector and exponentially increase the interval between two consecutive
checks in order to reduce the overhead of those checks.

We currently use fielddata on the `_id` field which is trappy, especially as we
do it implicitly. This changes the `random_score` function to use doc ids when
no seed is provided and to suggest a field when a seed is provided.

For now the change only emits a deprecation warning when no field is supplied
but this should be replaced by a strict check on 7.0.

Jason Tedor 4b18800df9 Fix handling of invalid error trace parameter
If a request contains an invalid error trace parameter, we send a error
on the channel. This should immediately abort any additional processing
of the request but instead we march on, dispatch the request and
subsequently send another message on the channel. The problem here is
this means two writes on the channel which leads to the request being
released twice ultimately raising in illegal reference count
exception. This commit addresses this by performing an early return in
the case that the request contained an invalid error trace parameter.

Boaz Leskes c0e6dafcab CombinedDeletionPolicy can't assert it has no commits when creating an index
This is an appealing assertion, but there scenarios where it can happen under normal operations. For example, when an index is created it may run into an exception when the lucene files have already been created. The master will try to assign the shard to another node (it's empty, so no need to look for data) but if there is no other node, it will reassign it to the same node. At that point the deletion will get a list of existing commits (which it will typically delete).

Luca Cavanna 5c5d723b86 Improve error message when aliases are not supported (#25728)
With #23997 and #25268 we have changed put alias, delete alias, update aliases and delete index to not accept aliases. Instead concrete indices should be provided as their index parameter.

This commit improves the error message in case aliases are provided, from an IndexNotFoundException (404 status code) with "no such index" message, to an IllegalArgumentException (400 status code) with "The provided expression [alias] matches an alias, specify the corresponding concrete indices instead." message.

Note that there is no specific error message for the case where wildcard expressions match one or more aliases. In fact, aliases are simply ignored when expanding wildcards for such APIs. An error is thrown only when the expression ends up matching no indices at all, and allow_no_indices is set to false. In that case the error is still the generic "404 - no such index".

Christoph Büscher a6e3d356ed Change parsing of numeric `to` and `from` parameters in `date_range` aggregation (#25376)
Currently the `to` and `from` parameter in the `date_range` aggregation is not
parsed with the correct date field format from the mappings or the aggregation
if the argument is numeric, but always treated as a long value specifying
`epoch_millis`. This leads to problems e.g. when the format is `epoch_second`,
but the `to` and `from` are currently treated as millis.

With this change, we interpret these parameters according to the `format` of the target field.
If the `format` in the mappings is not compatible with numeric input values,
a compatible `format` (e.g. `epoch_millis`, `epoch_second`) must be specified in
the `date_range` aggregation itself, otherwise an error is thrown.

Jason Tedor c63b7f8b0b Stop disabling explicit GC
The problem here is simple: when using direct buffers as in NIO, the JDK
relies on explict GC invocataions to trigger cleaning up direct buffers;
if such GCs do not occur and the direct buffer limit is reached, the JVM
will throw an out of memory exception. With explicit GCs disabled, the
JVM is neutered from explicitly cleaning up direct buffers in the act of
reserving a new direct buffer and instead relies on a GC occurring for
another reason. If such a GC never occurs, the JVM will OOM. This commit
removes disabling of explicit GCs. Note that these explicit GCs only
occur as a last ditch effort before going OOM when the JVM is trying to
reserve more direct memory. This is a known issue, see for example:
JDK-8142537.
