Today when an index is shrunk, the primary terms for its shards start
from one. Yet, this is a problem as the index will already contain
assigned sequence numbers across primary terms. To ensure document-level
sequence number semantics, the primary terms of the target shards must
start from the maximum of all the shards in the source index. This
commit causes this to be the case.

In MockFSDirectory we should use the actual indexes settings to build
a new IndexMetaData settings object instead of the node settings.

I'm still trying to hunt down rare failures in the cancelation tests
for reindex and friends. Here is the latest:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+5.x+multijob-unix-compatibility/os=ubuntu/876/console
It doesn't show much, other than that one of the tasks didn't kill
itself when asked to cancel.
So I'm going a bit crazy with debug logging so that the next time this
comes up I can trace exactly what happened.
Additionally, this tweaks the logic around how rethrottles were
performed around cancel. Previously we set the `requestsPerSecond`
to `0` when we cancelled the task. That was the "old way" to set them
to inifity which was the intent. This switches that from `0` to
`Float.MAX_VALUE` which is the "new way" to set the `requestsPerSecond`
to infinity. I don't know that this is much better, but it feels better.
In tests, we sometimes create a random directory service and as part of that the IndexSettings get
built again. When we build them again, we need to make sure we do not set the secure settings on
the new IndexMetaData object that gets created as the node settings already have the secure
settings and the index settings and node settings will be combined. If both have secure settings,
the settings builder will throw an AlreadySetException.
This commit fixes a typo in the KeyStoreCli class. The add-file command was incorrectly set to use
the AddStringKeyStoreCommand instead of the AddFileKeyStoreCommand.
Indexing or deleting documents through the IndexShard interface is quite complex and error-prone. It requires multiple calls, e.g. first prepareIndexOnPrimary, then do some checks if mapping updates have occurred, then do the actual indexing using index(...) etc. Currently each consumer of the interface (local recovery, peer recovery, replication) has additional custom checks built around it to deal with mapping updates, some of which are even inconsistent. This commit aims at reducing the complexity by exposing a simpler interface on IndexShard. There are no more prepare*** methods and the mapping complexity is also hidden, but still giving callers a possibility to implement custom logic to deal with mapping updates.
This commit changes the parsing logic of DocWriteResponse, ReplicationResponse
and GetResult so that it skips any unknown additional fields (for forward compatibility
reasons). This affects the IndexResponse, UpdateResponse,DeleteResponse and
GetResponse objects.
Today we maintain a map of open connections in order to close them when
a low level channel gets closed or handles a failure. We also spawn a thread due to some
tricky concurrency issues especially with respect to netty since they listener might
be called on a transport / boss thread. Executions on those threads must not be blocking
since otherwise we will likely deadlock the event processing which adds to the
complexity of the concurrency model in this class.
This change associates the connection with the close callback that every channel invokes
once it's closed which allows us to remove the connections map. A relaxed non-blocking
concurrency model in the connection close listener allows cleaning up connected nodes without
blocking on any lock.
* Add MSI installation to documentation
Move installation documentation for Windows with the .zip archive into the zip and tar installation documentation, and clearly indicate any differences for installing on macOS/Linux and Windows.
* Separate out installation with .zip on Windows
This test is failing because delete /{index} requests no longer support
index matching an alias. This commit removes testing such requests again
aliases.
Closes#25284
This change adds tests for the aggregation parsing that try to simulate that we
can parse existing aggregations in a forward compatible way in the future,
ignoring potential newly added fields or substructures to the xContent response.
Removes the `assemble` task from the `build` task when we have
removed `assemble` from the project. We removed `assemble` from
projects that aren't published so our releases will be faster. But
That broke CI because CI builds with `gradle precommit build` and,
it turns out, that `build` includes `check` and `assemble`. With
this change CI will only run `check` for projects without an
`assemble`.
Today TcpTransport is the de-facto base-class for transport implementations.
The need for all the callbacks we have in TransportServiceAdaptor are not necessary
anymore since we can simply have the logic inside the base class itself. This change
moves the stats metrics directly into TcpTransport removing the need for low level
bytes send / received callbacks.
Moves the keyword tokenizer to the analysis-common module. The keyword tokenizer is special because it is used by CustomNormalizerProvider so I pulled it out into its own PR. To get the move to work I've reworked the lookup from static to one using the AnalysisRegistry. This seems safe enough.
Part of #23658.
Removes the `assemble` task from projects that are not published.
This should speed up `gradle assemble` by skipping projects that
don't need to be built. Which is useful because `gradle assemble`
is how we cut releases.
With #23997 we have introduced a new internal index option that allows to resolve index expressions only against concrete indices while ignoring aliases. Such index option was applied to IndicesAliasesRequest, so that the index part of alias actions would only be resolved against concrete indices.
Same is done in this commit with delete index request. Deleting aliases has always been confusing as some users expect it to only remove the alias from the index (which has its own specific API). Even worse, in case of filtered aliases, deleting an alias may leave users with the expectation that only the documents that match the filter are deleted, which was never the case. To address all this confusion, delete index api works now only against concrete indices. WIldcard expressions will be only resolved against concrete index, as if aliases didn't exist. If one tries to delete against an alias, an IndexNotFoundException will be thrown regardless of whether the alias exists or not, as a concrete index with such a name doesn't exist.
Closes#2318
If a cluster is configured with an HDFS repository and a node is started, that node must be able
to reach HDFS, or else when it attempts to add the repository from the cluster state at start up
it will fail to connect and the repository will be left in an inconsistent state. Adding a blurb in the
docs to outline the expected availability for HDFS when using the repository plugin.
It adds notes about:
- how preference can help optimize cache usage
- the fact that too many replicas can hurt search performance due to lower
utilization of the filesystem cache
- how index sorting can improve _source compression
- how always putting fields in the same order in documents can improve _source
compression
* Add documentation for the new parent-join field
This commit adds the docs for the new parent-join field.
It explains how to define, index and query this new field.

UnicodeSetFilter was only allowed in the icu_folding token filter.
It seems useful to expose this setting in icu_normalizer token filter
and char filter.
This PR extends the TranslogDeletionPolicy to allow keeping the translog files longer than what is needed for recovery from lucene. Specifically, we allow specifying the total size of the files and their maximum age (i.e., keep up to 512MB but no longer than 12 hours). This will allow making ops based recoveries more common.
Note that the default size and age still set to 0, maintaining current behavior. This is needed as the other components in the system are not yet ready for a longer translog retention. I will adapt those in follow up PRs.

This commit does two things:
1. Adds logging at the DEBUG level for when the index-N blob is
updated.
2. When attempting to delete a snapshot, if the snapshot was not found
in the repository data, an exception is now thrown instead of silently
ignoring the lack of presence of the snapshot in the repository data.
