This makes the output of EsThreadPoolExecutor#toString less pretty but
we no longer have funky hacky that rely on the specific format of the
toString produced by ThreadPoolExecutor which isn't part of its API and
could change with any JVM version and break the output.
Improving the toString allows for nicer error reporting. Also cleaned up
the way that EsRejectedExecutionException notices that it was rejected
from a shutdown thread pool. I left javadocs about how its not 100% correct
but good enough for most uses.
The improved toString on EsThreadPoolExecutor mean every one of them needs
a name. In most cases the name to use is obvious. In tests I use the name
of the test method and in real thread pools I use the name of the thread
pool. In non-ThreadPool executors I use the thread's name.

In order to support the URL notation including a user/pass combination
(like http://user:pass@host/plugin.zip) the auth info needs to be added
manually.
The URL to download the main elasticsearch plugins did not match
what the S3 wageon is supposed to write to.
In addition this PR adds support for snapshots to access the
snapshot S3 bucket, so we can possibly download snapshot versions
of plugins.
The format of the URLs stems from #12270Closes#12632
Conflicting mappings that were allowed before v2.0 can cause runaway shard failures on upgrade. This commit adds a check that prevents a cluster from starting if it contains such indices as well as restoring such indices from a snapshot into already running cluster.
Closes#11857
Currently when we delete files belonging to deleted snapshots we issue one delete command to underlying snapshot store at a time. Some repositories can benefit from bulk deletes of multiple files.
Closes#12533
This method syncs the translog unless it's already synced. If the engine
is alreayd closed we are guaranteed to be synced already such that we can just
ignore this exception.
Closes#12603
this change was added recently which uses default timezone for the creation
date on CAT endpoints. We should be consistent and use UTC across the board.
This commit adds #getDefaultTimzone() to forbidden API and fixes the REST tests.
Relates to #11688
The Streams.copyTo(String|Bytes)FromClasspath() methods resolve resources using org.elasticsearch.io.Streams classloader. This is fine in elasticsearch core and when running tests but if used in a plugin this can lead to FileNotFoundExceptions at runtime because plugin are loaded in a dedicated classloader.
Most of the abstract base test classes we have were previously @Ignored.
However, there were also some other tests ignored. Having two ways to
quiet tests is confusing, and clearly it has caused some tests
to get lost in the fold.
This change moves all base test classes to use the "TestCase" suffix,
which is not picked up by the test class name pattern. It also removes
@Ignore from (almost) all tests, and adds it to forbidden apis.
And since we were renaming, I shorted base test class names to use
"ES" instead of "Elasticsearch". I type this a lot of types a day,
and I have heard others express a similar desire for a shorter name.

Now that integ tests are moved into `mvn verify`, we don't really have
a need for @Slow, and especially not @Integration. This removes
uses of the first, and completely removes uses of the latter.
Tasks can be registered with a timeout, which runs as a task in a separate
threadpool. The idea is that the timeout runner cancels the main task when
the time is out, and the timeout runner is cancelled when the main task
starts executing. However, the following statement:
```java
timeoutFuture = timer.schedule(new Runnable() {
@Override
public void run() {
if (remove(TieBreakingPrioritizedRunnable.this)) {
runAndClean(timeoutCallback);
}
}
}, timeValue.nanos(), TimeUnit.NANOSECONDS);
```
is not atomic: the removal task is first started, and then the (volatile)
variable is assigned. As a consequence, there is a short window that allows
a timeout task to wait until the time is out even if the task is already
completed.
See http://build-us-00.elastic.co/job/es_core_17_centos/496/ for an example of
such a failure.
Previously only the first aggregation in a buckets_path was check to make sure the aggregation existed. Now the whole path is checked to ensure an aggregation exists at each element in the buckets_path
Closes#12360
Its not going to work: its blocked by security policy
and will just add a confusing SecurityException to the mix, and
bogusly give an exit status of 0 when in fact something bad happened.
Finally, if ES can't startup, it is a serious problem, there is
no sense in hiding the reason why: deliver the full stack trace.
The repository verification process should create a subdirectory to make sure we check permission of newly created directories in case elasticsearch processes on different nodes are running using different uids and creating blobs with incompatible permissions.
Closes#11611
Previously we issued a reroute when a node went over the high watermark
in order to move shards away from the node. This change tracks nodes
that have previously been over the high or low watermarks and issues a
reroute when the node goes back underneath the watermark.
This allows shards that may be unassigned to be assigned back to a node
that was previously over the low watermark but no longer is.
Resolves#12422
