We already deprecated and removed the camel-case versions of the nGram and edgeNGram
filters a while ago and we should do the same with the nGram and edgeNGram tokenizers.
This PR deprecates the use of these names in favour of ngram and edge_ngram in 7
and disallows usage in new indices starting with 8.
Closes#50561
The cat nodes API performs a `ClusterStateAction` then a `NodesInfoAction`.
Today it accepts the `?local` parameter and passes this to the
`ClusterStateAction` but this parameter has no effect on the `NodesInfoAction`.
This is surprising, because `GET _cat/nodes?local` looks like it might be a
completely local call but in fact it still depends on every node in the
cluster.
This parameter was deprecated in 7.x in #50499 and this commit removes it.

Follow up to #48368. This PR removes support for `sparse_vector` on new
indices. On 7.x indices a `sparse_vector` can still be defined, but it is not
possible to index or search on it.
This commit makes it an error to start a node where either of the
server contexts (xpack.security.transport.ssl and
xpack.security.http.ssl) meet either of these conditions:
1. The server lacks a certificate/key pair (i.e. neither
ssl.keystore.path not ssl.certificate are configured)
2. The server has some ssl configuration, but ssl.enabled is not
specified. This new validation does not care whether ssl.enabled is
true or false (though other validation might), it simply makes it
an error to configure server SSL without being explicit about
whether to enable that configuration.
The endpoints with `_xpack` in their path were deprecated in 7.x and can now be
removed. This commit removes deprecated endpoints for the following APIs:
* deprecation
* graph
* license
* monitoring
* rollup
* SQL
* watcher
Setting `cluster.routing.allocation.disk.include_relocations` to `false` is a
bad idea since it will lead to the kinds of overshoot that were otherwise fixed
in #46079. This setting was deprecated in #47443. This commit removes it.
After deprecating the `enabled` setting for `_field_names`starting with 7.5,
this change disallows the setting on new indices in 8.0. The setting continues
to work for indices created in 7.x where we continue emitting a deprecation warning.

This commit removes types from the ShardGetService, and propagates this API change
up through the Transport and Rest actions for Get and MultiGet
Relates to #41059
With this commit, Elasticsearch will no longer prefer using shards in the same location
(with the same awareness attribute values) to process `_search` and `_get` requests.
Instead, adaptive replica selection (the default since 7.0) should route requests more efficiently
using the service time of prior inter-node communications. Clusters with big latencies between
nodes should switch to cross cluster replication to isolate nodes within the same zone.
Note that this change only targets 8.0 since it is considered as breaking. However a follow up
pr should add an option to activate this behavior in 7.x in order to allow users to opt-in early.
Closes#43453
The internal configuration settings were like that: network.breaker.inflight_requests
But the exposed REST API had the value names with underscore like that: network.breaker.in_flight_requests
This was now corrected to without underscores like that: network.breaker.inflight_requests
The processors setting was deprecated in version 7.4.0 of Elasticsearch
for removal in Elasticsearch 8.0.0. This commit removes the processors
setting.
Removes support for using a system property to disable the automatic release of
the write block applied when a node exceeds the flood-stage watermark.

This commit changes the ForceMergeRequest.validate() method so that it does
not accept the parameters only_expunge_deletes and max_num_segments
to be set at the same time.
The motivation is that InternalEngine.forceMerge() just ignores the max. number
of segments parameter when the only expunge parameter is set to true, leaving
the wrong impression to the user that max. number of segments has been applied.
It also changes InternalEngine.forceMerge() so that it now throws an exception
when both parameters are set, and modifies tests where needed.
Because it changes the behavior of the REST API I marked this as >breaking.
Closes#43102
Today we fail the node at startup if it contains an index that is too old to be
compatible with the current version, unless that index is closed. If the index
is closed then the node will start up and this puts us into a bad state: the
index cannot be opened and must be reindexed using an earlier version, but we
offer no way to get that index into a node running an earlier version so that
it can be reindexed. Downgrading the node in-place is decidedly unsupported and
cannot be expected to work since the node already started up and upgraded the
rest of its metadata. Since #41731 we actively reject downgrades to versions ≥
v7.2.0 too.
This commit prevents the node from starting in the presence of any too-old
indices (closed or not). In particular, it does not write any upgraded metadata
in this situation, increasing the chances an in-place downgrade might be
successful. We still actively reject the downgrade using #41731, because we
wrote the node metadata file before checking the index metadata, but at least
there is a way to override this check.

Now that the transport client has been removed, the client transport
profile filter can be removed from security. This filter prevented node
actions from being executed using a transport client.
This commit removes the nested_path and nested_filter options deprecated in 6x.
This change also checks that the sort field has a [nested] option if it is under a nested
object and throws an exception if it's not the case.

This commit finalizes the work done to rename size to max_docs in
reindex and update/delete by query. size is no longer supported in URL
or outer level body for the 3 APIs (though size in update/delete-by-query
will and has always been interpreted as scroll_size, it is not to be relied
upon).
Continuation of #41894Closes#24344
#42090 PR added support
for requesting snapshots from multiple repositories. And it has changed
the response format in a non-BwC way.
There is a mentioning of a response format change in the breaking
changes docs, however, there is no example of how new format looks
like. Pointed out by @dakrone.
This commit adds the missing example.
This commit adds multiple repositories support to get snapshots
request.
If some repository throws an exception this method does not fail fast
instead, it returns results for all repositories.
This PR is opened in favour of #41799, because we decided to change
the response format in a non-BwC manner. It makes sense to read a
discussion of the aforementioned PR.
This is the continuation of work done here #15151.
Remove `common` query and `cutoff_frequency` parameter of
`match` and `multi_match` queries. Both have already been
deprecated for the next 7.x version.
Closes: #37096
With the removal of node.max_local_storage_nodes, there is no need anymore to keep the data in
subfolders indexed by a node ordinal. This commit makes it so that ES 8.0 will store data directly in
$DATA_DIR instead of $DATA_DIR/nodes/$nodeOrdinal.
Upon startup, Elasticsearch will check to see if there is data in the old location, and automatically
move it to the new location. This automatic migration only works if $nodeOrdinal is 0, i.e., multiple
node instances have not previously run on the same data path, which required for
node.max_local_storage_nodes to explicitly be configured.
We deprecated these settings awhile ago, in favor of cluster.remote. In
7.x we were gentle and provided automatic upgrade of these settings to
the new settings. Now it is time for them to go. This commit removes the
deprecated search.remote settings.
This setting, which prior to Elasticsearch 5 was enabled by default and caused all kinds of
confusion, has since been disabled by default and is not recommended for production use. The
preferred way going forward is for users to explicitly specify separate data folders for each started
node to ensure that each node is consistently assigned to the same data path.

This commit removes the deprecated migrate tool which was used to
migrate users from the file realm to native realm when the native realm
was first created.
Removed the leniency when encoding remote reindex search requests that

to the remote host.
Follow-up to #40303
This is related to #36652. There are a number of transport settings that
were deprecated and replaced with new versions in 7.x. This commit
removes them from 8.0.
The current java implementation of Fuzziness leaves a lot of room for
initializing it with illegal values that either cause errors later when the
queries reach the shards where they are executed or values that are silently
ignored in favour of defaults. We should instead tighten the java implementation
of the class so that we only accept supported values. Currently those are
numeric values representing the edit distances 0, 1 and 2, optionally also as
float or string, and the "AUTO" fuzziness, which can come in a cusomizable
variant that allows specifying two value that define the positions in a term
where the AUTO option increases the allowed edit distance.
This change removes several redundant ways of object construction and adds input
validation to the remaining ones. Java users should either use one of the
predefined constants or use the static factory methods `fromEdits(int)` or
`fromString(String)` to create instances of the class, while other ctors are
hidden. This allows for instance control, e.g. returning one of the constants
when creating instances from an integer value.
Previously the class would accept any positive integer value and any float
value, while in effect the maximum allowed edit distance was capped at 2 in
practice. These values while throw an error now, as will any other String value
other than "AUTO" that where previously accepted but led to numeric exceptions
when the query was executed.
