Using the infra that we now have in place, we can convert the low-level REST client docs so that they extract code snippets from real Java classes. This way we make sure that all the snippets properly compile. Compared to the high level REST client docs, in this case we don't run the tests themselves, as that would require depending on test-framework which requires java 8 while the low-level REST client is compatible with java 7. I think that compiling snippets is enough for now.
Some tests use MockTransportService to do network based testing.
Yet, we run tests in multiple JVMs that means
concurrent tests could claim port that another JVM just released
and if that test tries to simulate a disconnect it might be smart
enough to re-connect depending on what is tested. To reduce the risk,
since this is very hard to debug we use a different default
port range per JVM unless the incoming settings overriding it.
Closes#25301
* Refactor PathTrie and RestController to use a single trie for all methods
This changes `PathTrie` and `RestController` to use a single `PathTrie` for all
endpoints, it also allows retrieving the endpoints' supported HTTP methods more
easily.
This is a spin-off and prerequisite of #24437
* Use EnumSet instead of multiple if conditions
* Make MethodHandlers package-private and final
* Remove duplicate registerHandler method
* Remove public modifier
Today when we run out of disk all kinds of crazy things can happen
and nodes are becoming hard to maintain once out of disk is hit.
While we try to move shards away if we hit watermarks this might not
be possible in many situations. Based on the discussion in #24299
this change monitors disk utilization and adds a flood-stage watermark
that causes all indices that are allocated on a node hitting the flood-stage
mark to be switched read-only (with the option to be deleted). This allows users to react on the low disk
situation while subsequent write requests will be rejected. Users can switch
individual indices read-write once the situation is sorted out. There is no
automatic read-write switch once the node has enough space. This requires
user interaction.
The flood-stage watermark is set to `95%` utilization by default.
Closes#24299
This commit causes a replica to throwback its local checkpoint to the
global checkpoint when learning of a new primary through a replica
operation.

In 6.x we prevent multiple types and default to `index.mapping.single_type: false`
This change removes the registered setting and ensures that it's preserved for
5.x indices.

Add an Important admonition for upgrading via the command line
using the Windows MSI Installer. This calls out the need to pass
the same command line options for an upgrade as were used for
the initial installation.
All query builders written as self contained xContent objects, to we should mark
them accordingly using ToXContentObject. This also makes it possible to use
things like XContentHelper#toXContent to render query builders in tests.
* Adds rewrite phase to aggregations
This change adds aggregations to the rewrite performed by the `SearchSourceBuilder`. This means that `AggregationBuilder`s are able to implement a `rewrite()` method where they can return a new `AggregationBuilder` which is functionally the same but in a more primitive form. This is exactly analogous to the rewrite done by the `QueryBuilder`s.
The first aggregation to implement the rewrite are the filter and filters aggregations so they can rewrite the filters they contain.
Closes#17676
* Removes rewrite from PipelineAggregationBuilder
Rewrite is based on shard level information. Since pipeline aggregation are run in the reduce phase it doesn’t make sense to rewrite them on the shards. In fact eventually we shouldn’t be transporting them to the shards at all and should be retaining them on the coordinating node for execution in the reduce phase
* Addresses review comments
* addresses more review comments
* Fixed imports
The constructor using `types` has been deprecated for a while now (starting with
ES 5.1.). It can be removed in the next mayor version. Since types are optional
they should be added with the #types() setter.
* Adds check for negative search request size
This change adds a check to `SearchSourceBuilder` to throw and exception if the size set on it is set to a negative value.
Closes#22530
* fix error in reindex
* update re-index tests
* Addresses review comment
* Fixed tests
* Added random negative size test
* Fixes test
This commit converts the low level client and high level client chapters into two parts, which allows each high level client supported api to be on a separate page and show up in the index on the right.
QueryParseContext is currently only used as a wrapper for an XContentParser, so
this change removes it entirely and changes the appropriate APIs that use it so
far to only accept a parser instead.
We have two ways to filter XContent:
- The first method is to parse the XContent as a map and use
XContentMapValues.filter(). This method filters the content of the map
using an automaton. It is used for source filtering, both at search and
indexing time. It performs well but can generate a lot of objects and
garbage collections when large XContent are filtered. It also returns
empty objects (see f2710c16eb) when all
the sub fields have been filtered out and handle dots in field names as
if they were sub fields.
- The second method is to parse the XContent and copy the XContentParser
structure to a XContentBuilder initialized with includes/excludes
filters. This method uses the Jackson streaming filter feature. It is
used by the Response Filtering ('filter_path') feature. It does not
generate a lot of objects, and does not return empty objects and also
does not handle dots in field names explicitely.
Both methods have similar goals but different tests. This commit changes
the current XContentBuilder test class so that it becomes a more generic
testing class and we can now ensure that filtering methods generate the
same results.
It also removes some tests from the XContentMapValuesTests class that
should be in XContentParserTests.
The significance aggs return Lucene index-level statistics that when merged are assumed to be from different shards. The Aggregator unit tests assume segments can be treated as shards and thus break the significance stats and introduce double-counting of background doc frequencies. This change addresses this problem by ensuring test indexes have only one shard.
Closes#25429
If all nodes get disconnected before we can send the request we might
try to reconnect and that will fail with an ISE instead of the a transport
exception.

ensureYellow ensures at least yellow.
Also, since we only have 1 replica, we don't need to index for it to know about the primary term promotion

This commit makes the use of the global network settings explicit instead
of implicit within NetworkService. It cleans up several places where we fall
back to the global settings while we should have used tcp or http ones.
In addition this change also removes unnecessary settings classes
The replica replication response object has an extra allocationId field that contains the allocation id of the replica on which the request was executed. As we are sending the allocation id with the actual replica replication request, and check when executing the replica replication action that the allocation id of the replica shard is what we expect, there is no need to communicate back the allocation id as part of the response object.
This commit adjusts the BWC version on the bad cluster allocation
explain request test as changing the API to respond with a bad request
status instead of an internal server error status was backported to 5.x
to be included in 5.6.0.

Hadoop 2.7.x libraries fail when running on JDK9 due to the version string changing to a single
character. On Hadoop 2.8, this is no longer a problem, and it is unclear on whether the fix will be
backported to the 2.7 branch. This commit upgrades our dependency of Hadoop for the HDFS
Repository to 2.8.1.
When a user requests a cluster allocation explain in a situation where
it does not make sense (for example, there are no unassigned shards), we
should consider this a bad request instead of a server error. Yet, today
by throwing an illegal state exception, these are treated as server
errors. This commit adjusts these so that they throw illegal argument
exceptions and are treated as bad requests.
