This can happen for a number of reasons, including bugs.
Today you will get a super crappy failure, telling you a .pid file
was not found... you can go look in target/integ-tests/elasticsearch-xxx/logs
and examine the log file, but thats kinda a pain and not easy if its a jenkins
server.
Instead we can fail like this:
```

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.
