We are still chasing a test failure here and increasing the logging
level stopped the failures. We have a theory as to what is going on so
this commit reduces the logging level to hopefully trigger the failure
again and give us the logging that we need to confirm the theory.
Use fedora-25 Vagrant box in VagrantTestPlugin, which was missing from
9a3ab3e800 causing packaging test
failures.
Additionally update TESTING.asciidoc
This is a follow-up to #24317, which did the hard work but was merged in such a
way that it exposes the setting while still allowing indices to have multiple
types by default in order to give time to people who test against master to
add this setting to their index settings.
This test started failing but the logging here is insufficient to
discern what is happening. This commit increases the logging level on
this test until the failure can be understood.
In pre-release versions of Elasticsearch 5.0.0, users were subject to
log messages of the form "your platform does not.*reliably.*potential
system instability". This is because we disable Netty from being unsafe,
and Netty throws up this scary info-level message when unsafe is
unavailable, even if it was unavailable because the user requested that
it be unavailabe. Users were rightly confused, and concerned. So, we
contributed a guard to Netty to prevent this log message from showing up
when unsafe was explicitly disabled. This guard shipped with all
versions of Netty that shipped starting with Elasticsearch
5.0.0. Unfortunately, this guard was lost in an unrelated refactoring
and now with the 4.1.10.Final upgrade, users will again see this
message. This commit is a hack around this until we can get a fix
upstream again.

The UpgraderPlugin adds two additional extension points called during cluster upgrade and when old indices are introduced into the cluster state during initial recovery, restore from a snapshot or as a dangling index. One extension point allows plugin to update old templates and another extension points allows to update/check index metadata.
Currently the only implementation of `ListenableActionFuture` requires
dispatching listener execution to a thread pool. This commit renames
that variant to `DispatchingListenableActionFuture` and converts
`AbstractListenableActionFuture` to be a variant that does not require
dispatching. That class is now named `PlainListenableActionFuture`.
The DiscoveryNodesProvider interface provides an unnecessary abstraction and is just used in conjunction with the existing PingContextProvider interface. This commit removes it.
Open/Close index api have allow_no_indices set to false by default, while delete index has it set to true. The flag controls where a wildcard expression that matches no indices will be ignored or an error will be thrown instead. This commit aligns open/close default behaviour to that of delete index.
This field was only ever used in the constructor, where it was set and
then passed around. As such, there's no need for it to be a field and we
can remove it.
Add info about the base image used and the github repo of
elasticsearch-docker.
Clarify that setting `memlock=-1:-1` is only a requirement when
`bootstrap_memory_lock=true` and the alternatives we document
elsewhere in docs for disabling swap are valid for Docker as well.
Additionally, with latest versions of docker-ce shipping with
unlimited (or high enough) defaults for `nofile` and `nproc`, clarify
that explicitly setting those per ES container is not required, unless
they are not defined in the Docker daemon.
Finally simplify production `docker-compose.yml` example by removing
unneeded options.

After a replica shard finishes recovery, it will be marked as active and
its local checkpoint will be considered in the calculation of the global
checkpoint on the primary. If there were operations in flight during
recovery, when the replica is activated its local checkpoint could be
lagging behind the global checkpoint on the primary. This means that
when the replica shard is activated, we can end up in a situtaion where
a global checkpoint update would want to move the global checkpoint
backwards, violating an invariant of the system. This only arises if a
background global checkpoint sync executes, which today is only a
scheduled operation and might be delayed until the in-flight operations
complete and the replica catches up to the primary. Yet, we are going to
move to inlining global checkpoints which will cause this issue to be
more likely to manifest. Additionally, the global checkpoint on the
replica, which is the local knowledge on the replica updated under the
mandate of the primary, could be higher than the local checkpoint on the
replica, again violating an invariant of the system. This commit
addresses these issues by blocking global checkpoint on the primary when
a replica shard is finalizing recovery. While we have blocked global
checkpoint advancement, recovery on the replica shard will not be
considered complete until its local checkpoint advances to the blocked
global checkpoint.

today we only lookup nodes by their ID but never by the (clusterAlias, nodeId) tuple.
This could in theory lead to lookups on the wrong cluster if there are 2 clusters
with a node that has the same ID. It's very unlikely to happen but we now can clearly
disambiguate between clusters and their nodes.
This change makes the request builder code-path same as `Client#execute`. The request builder used to return a `ListenableActionFuture` when calling execute, which allows to associate listeners with the returned future. For async execution though it is recommended to use the `execute` method that accepts an `ActionListener`, like users would do when using `Client#execute`.

Async shard fetching only uses the node id to correlate responses to requests. This can lead to a situation where a response from an earlier request is mistaken as response from a new request when a node is restarted. This commit adds unique round ids to correlate responses to requests.
We often want the JVM arguments used for a running instance of
Elasticsearch. It sure would be nice if these came as part of the nodes
API, or any API that includes JVM info. This commit causes these
arguments to be displayed.
Relates #24450
These can be very useful to have, let's have them at our fingertips in
the logs (in case the JVM dies and we can no longer retrieve them, at
least they are here).

* Fix JVM test argline
The argline was being overridden by '-XX:-OmitStackTraceInFastThrow'
which led to test failures that were expecting the JVM to be in a
certain state based on the value of tests.jvm.argline but they were not
since these arguments were never passed to the JVM. Additionally, we
need to respect the provided JVM argline if it is already provided with
a flag for OmitStackTraceInFastThrow. This commit fixes this by only
setting OmitStackTraceInFastThrow if it is not already set.

We've had `QueryDSLDocumentationTests` for a while but it had a very
hopeful comment at the top about how we want to make sure that the
example in the query-dsl docs match up with the test but we never
had anything that made *sure* that they did. This changes that!
Now the examples from the query-dsl docs are all built from the
`QueryDSLDocumentationTests`. All except for the percolator example
because that is hard to do as it stands now.
To make this easier this change moves `QueryDSLDocumentationTests`
from core and into the high level rest client. This is useful for
two reasons:
1. We expect the high level rest client to be able to use the builders.
2. The code that builds that docs doesn't check out all of
Elasticsearch. It only checks out certain directories. Since we're
already including snippets from that directory we don't have to
make any changes to that process.
Closes#24320
TransportService and RemoteClusterService are closely coupled already today
and to simplify remote cluster integration down the road it can be a direct
dependency of TransportService. This change moves RemoteClusterService into
TransportService with the goal to make it a hidden implementation detail
of TransportService in followup changes.
The license header in this file was after and on the same line as the
package statement. This commit moves the package statement to be after
the license header.
This adds `-XX:-OmitStackTraceInFastThrow` to the JVM arguments
which *should* prevent the JVM from omitting stack traces on
common exception sites. Even though these sites are common, we'd
still like the exceptions to debug them.
This also adds the flag when running tests and adapts some tests
that had workarounds for the absense of the flag.
Closes#24376
RemoteClusterService is an internal service that should not necessarily be exposed
to plugins or other parts of the system. Yet, for cluster name parsing for instance
it is crucial to reuse some code that is used for the RemoteClusterService. This
change extracts a base class that allows to share the settings related code as well
as cluster settings updates to `search.remote.*` to be observed by other services.
* Fixes#24259
Corrects the ScriptedMetricAggregator so that the script can have
access to scores during the map stage.
* Restored original tests. Added seperate test.
As requested, I've restored the non-score dependant tests, and added the
score dependent metric as a seperate test.
