When a node get disconnected from the cluster and rejoins during a master election, it may be that the new master already has that node in it's cluster and will try to assign it shards. If the node hosts started primaries, the new shards will be initializing and will have the same allocation id as the allocation ids of the current started size. We currently do not recognize this currently. We should clean the current IndexShard instances and initialize new ones.
This also hardens test assertions in the same area.
This makes geo-distance sorting use `LatLonDocValuesField.newDistanceSort`
whenever applicable, which should be faster that the current approach since it
tracks a bounding box that documents need to be in in order to be competitive
instead of doing a costly distance computation all the time.
Closes#20450
today it's not possible to use date-math efficiently with the `_rollover`
API. This change adds support for date-math in the target index as well as
support for preserving the math logic when an existing index that was created with
a date math expression all subsequent indices are created with the same expression.
Right now our unit tests in that area only simulate indexing single documents. As we go forward it should be easy
to add other actions, like delete & bulk indexing. This commit extracts the common parts of the current indexing
logic to a based class make it easier to extend.
The Setting.timeValue() method uses TimeValue.toString() which can produce fractional time values. These fractional time values cannot be parsed again by the settings framework.
This commit fix a method that still use the .toString() method and replaces it with .getStringRep(). It also changes a second method so that it's not up to the caller to decide which stringify method to call.

This commit fixes a failing cluster settings tests, namely the logger
level update test. The test was incorrectly assuming the default log
level was info, but it could be non-info, for example, if
tests.es.logger.level is set to some non-info level.
Closes#20318
The logging listener tests started failing after
953a8a959b when the tests are run with
tests.es.logger.level set to any level other than debug. This is because
these tests were based around the assumption that the default logging
level was info, which was the case before that commit fixed setting the
default logging level via that system property. This commit fixes these
failing tests by adjusting this assumption to account for the fact that
the default logging level could be different.
Today we allow system bootstrap checks to be ignored with a
setting. Yet, the system bootstrap checks are as vital to the health of
a production node as the non-system checks (e.g., the original bootstrap
check, the file descriptor check, is critical for reducing the chances
of data loss from being too low). This commit removes the ability to
ignore system bootstrap checks.

The invalid ingest configuration field name used to show itself,
even when it was null, in error messages. Sometimes this does not make
sense.
e.g.
```[null] Only one of [file], [id], or [inline] may be configure```
vs.
```Only one of [file], [id], or [inline] may be configure```
The above deals with three fields, therefore this no one property
responsible.
this change adds a hard limit to `index.number_of_shard` that prevents
indices from being created that have more than 1024 shards. This is still
a huge limit and can only be changed via settings a system property.
Pipe in the `tests.es.logger.level` system property to the log4j config file used in tests. We still default to info. Also adapts the logger name to use the first letter of packages.
Today when getting setting via an API like the cluster settings API,
complex settings are excluded (e.g.,
discovery.zen.ping.unicast.hosts). This commit adds these settings to
the output of such APIs.

It currently returns something like:
```
"No feature for name [_siohgjoidfhjfihfg]"
```
Which is not the most understandable message, this changes it to be a
little more readable.

We were swallowing the original exception when creating a client with bad credentials.
So even in `TRACE` log level, nothing useful were coming out of it.
With this commit, it now prints:
```
[2016-09-27 15:54:13,118][ERROR][cloud.azure.storage ] [node_s0] can not create azure storage client: Storage Key is not a valid base64 encoded string.
```
Closes#20633.
Backport of #20669 for master branch (6.0)
Today when executing the install plugin command without a plugin id, we
end up throwing an NPE because the plugin id is null yet we just keep
going (ultimatley we try to lookup the null plugin id in a set, the
direct cause of the NPE). This commit modifies the install command so
that a missing plugin id is detected and help is provided to the user.

Surprise! You can use sliced scroll to easily parallelize reindex
and friend. They support it because they use the same infrastructure
as a regular search to parse the search request. While we would like
to make an "automatic" option for parallelizing reindex, this manual
option works right now and is pretty convenient!
reindex-from-remote should ignore unknown fields so it is mostly
future compatible. This makes it ignore unknown fields by adding an
option to `ObjectParser` and `ConstructingObjectParser` that, if
enabled, causes them to ignore unknown fields.
Closes#20504
Many of our unit tests instantiate an `AllocationService`, which requires having a `GatewayAllocator`. Today almost all of our test use a class called `NoopGatewayAllocator` which does nothing, effectively leaving all shard assignments to the balanced allocator. This is sad as it means we test a system that behaves differently than our production logic in very basic things. For example, a started primary that is lost will be assigned to a node that didn't use to have it.
This PR removes `NoopGatewayAllocator` in favor of a new `TestGatewayAllocator` that inherits the standard `GatewayAllocator` and overrides shard information fetching to return information based on historical assignments the allocator has done. The only exception is `BalanceConfigurationTests` which does test only the balancer and I opted to not have it work around the `GatewayAllocator` being in it's way.
This commit fixes the documentation for configuring the Java I/O temp
dir which incorrectly suggested using the -D flag as a parameter on the
command line; these flags have been removed and should now be specified
as arguments to the JVM using either the ES_JAVA_OPTS environment
variable or using the jvm.options configuration file.
Closes#20652
Changes the API of GatewayAllocator#applyStartedShards and
GatewayAllocator#applyFailedShards to take both a RoutingAllocation
and a list of shards to apply. This allows better mock allocators
to be created as being done in #20637.
Closes#20642
Removes the FailedRerouteAllocation class and StartedRerouteAllocation
class, as they were just wrappers for RerouteAllocation that stored
started and failed shards, but these started and failed shards can
be passed in directly to the methods that needed them, removing the
need for this wrapper class and extra level of indirection.
Closes#20626
When initializing a new index routing table, we make a decision where the primary shards should be recovered from. This can be an empty folder for new indices, a set of specific allocation ids for old indices or a snapshot. We currently allow callers of `IndexRoutingTable.initializeEmpty` to supply the source but also set it automatically if null is given. Sadly the current logic is reusing the supplied parameter to store the result of the automatic decision. This is flawed if some of the decision should be *different* between the different index shard (as the first decision that is maid sticks).
This commit fixes this but also simplifies the API to always make an automatic decision.
This was discovered while working on #20637 which strengthens the testing infra and caused this to bubble up. I put it as a separate commit to make sure it is not lost as part of a bigger test only PR.
* Removed the check for the correct hash in the `/` response, otherwise two hashes would be needed
* Adapted to new URLs
* Added two missing plugins
* Downloaded gpg key only once
Today we hold on to all possible tokenizers, tokenfilters etc. when we create
an index service on a node. This was mainly done to allow the `_analyze` API to
directly access all these primitive. We fixed this in #19827 and can now get rid of
the AnalysisService entirely and replace it with a simple map like class. This
ensures we don't create a gazillion long living objects that are entirely useless since
they are never used in most of the indices. Also those objects might consume a considerable
amount of memory since they might load stopwords or synonyms etc.
Closes#19828
