Instead of `search.remote.seeds.${clustername}` we now specify the seeds as:
`search.remote.${clustername}.seeds` which is a real list setting compared to an unvalidated
group setting before.
Fix the `Dockerfile` example in the `Customizing image` third configuration
method by adding the missing RUN instruction.

Today affix settings are not dynamic since it's required to know
it's namespace in order to pull a concrete setting from it. This is not possible
in practice since the namespaces are dynamic by design. This change allows to register
a specialized settings consumer that consumes the namespace and the actual value if
a setting gets updated.
Moves fetching the local node id into `NodeClient` which is a
fairly useful place to put it so you can generate task ids from
`NodeClient#executeLocally`.
This commit reverts switching to the unpooled allocator (for now) to let
some benchmarks run to see if this is the source of an increase in GC
times.

This commit adds the parsing fromXContent() methods to the IndexResponse class. The method is based on a ObjectParser because it is easier to use when parsing parent abstract classes like DocWriteResponse.
It also changes the ReplicationResponse.ShardInfo so that it now implements ToXContentObject. This way, the ShardInfo.fromXContent() method can be used by the IndexResponse's ObjectParser.
Previously, we removed all unneeded backward compatibility logic
from the BlobStoreRepository because 6.0 does not need to support
2.x snapshot formats. During the process of removing this backward
compatibility logic, some code was leftover that is no longer
necessary. This commit removes all the remaining unnecessary
backwards compatibility code in BlobStoreRepository.
#9261 added a warning about the use of `add-apt-repository` which is becoming obsolete over time as new distribution releases include later versions of `add-apt-repository` which don't automatically add the `deb-src` line. This change updates the documentation to make the block a note rather than a warning and adds two other reasons for avoiding `add-apt-repository` which are still relevant: avoiding edits to a system shared file and not requiring a large number of non-default packages to add one line of text to a file.
The example
```
/<logstash-{now/d-2d}>,<logstash-{now/d-1d}>,<logstash-{now/d}>/_search
```
shows escaped URL where `, => %2C`, so I assume it should be escaped and be present in the table
It is no longer needed. It used to contain a lot of strings
used by serialization but those have since been removed. Now
it is just another thing to pass around that we don't really
need.
Reindex-from-remote had a race when it tried to clear the scroll. It
first starts the request to clear the scroll and then submits a task
to the generic threadpool to shutdown the client. These two things
race and, in my experience, closing the scroll generally loses. That
means that most of the time reindex-from-remote isn't clearing the
scrolls that it uses. This isn't the end of the world because we
flush old scroll contexts after a while but this isn't great.
Noticed while experimenting with #22514.
This commit updates the cluster allocation explain API documentation to
explain the new request parameters and response formats, and gives
examples of the explain API responses under various scenarios.
Affix settings are useful to namespace a certain setting. Yet, affix settings
must be specialized for their concrete type which causes lot of code duplication.
This commit allows to reuse an existing setting with and affix setting as soon as
a concrete key is available.
Reindex-from-remote was accepting source filtering in the request
but ignoring it and setting `_source=true` on the search URI. This
fixes the filtering so it is piped through to the remote node and
adds tests for that.
Closes#22507
One needs to close the higher level objects (like UnicastZenPing) before closing the transport service. The latter can throw assertions w.r.t open connections
This adds methods to parse InternalSearchHit and InternalSearchHits from their
xContent representation. Most of the information in the original object is
preserved when rendering the object to xContent and then parsing it back.
However, some pieces of information are lost which we currently cannot parse
back from the rest response, most notably:
* the "match" property of the lucene explanation is not rendered in the
"_explain" section and cannot be reconstructed on the client side
* the original "shard" information (SearchShardTarget) is only rendered if the
"explanation" is also set, also we loose the indexUUID of the contained
ShardId because we don't write it out. As a replacement we can use
ClusterState.UNKNOWN_UUID on the receiving side
The NodeConnectionsService currently determines which nodes to connect to / disconnect from by inspecting cluster state changes and connecting to added nodes / disconnecting from removed nodes. When a master steps down (for example due to another master-eligible node shutting down which brings the number of master-eligible nodes below minimum_master_master), and the connection to other existing nodes was dropped while pinging, however, the connection to these nodes is not re-established while publishing the first cluster state that establishes the node as master.
This commit changes the NodeConnectionsService connect / disconnect logic to always rely on the state that is to be / was published, looking not only at the added / removed nodes, but validating that exactly all nodes that are currently registered in NodeConnectionsService are connected (corresponds to a NOOP if the node is already connected).
This commit adds a document describing our data replication model in high level terms. The goal is give people basic insight into how things work in order to better understand how read and writes interact, both during normal operations and under failures.
The document in the randomized GetResult can exist with no source (like if the _source was disabled in mappings), that's why the test should not always expect a non null source when the doc exists.
* Promote longs to doubles when a terms agg mixes decimal and non-decimal number
This change makes the terms aggregation work when the buckets coming from different indices are a mix of decimal numbers and non-decimal numbers. In this case non-decimal number (longs) are promoted to decimal (double) which can result in a loss of precision for big numbers.
Fixes#22232
There is a bug in the error message that is thrown if the number of docs differs between the source and target shards when recovering a shard with a syncId. The source and target doc counts are swapped around.
Closes#21893
Currently, such tasks are only created for default boxes (centos-7, ubuntu-1404) and not all boxes and this can be misleading for developers who want to debug testing scripts on non-default boxes.
