Adds a message about how the remote is unlikely to be Elasticsearch.
This isn't as good as including the whole message from the remote but
we can't do that because we are stream parsing it and we don't want
to mark the whole request.
Closes#22330
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`.
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.
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
Removes `AggregatorParsers`, replacing all of its functionality with
`XContentParser#namedObject`.
This is the third bit of payoff from #22003, one less thing to pass
around the entire application.
If the remote doesn't return a content type then reindex
tried to guess the content-type. This didn't work most
of the time and produced a rather useless error message.
Given that Elasticsearch always returns the content-type
we are dropping content-type detection in favor of just
failing the request if the remote didn't return a content-type.
Closes#22329
* Remove a checked exception, replacing it with `ParsingException`.
* Remove all Parser classes for the yaml sections, replacing them with static methods.
* Remove `ClientYamlTestFragmentParser`. Isn't used any more.
* Remove `ClientYamlTestSuiteParseContext`, replacing it with some static utility methods.
I did not rewrite the parsers using `ObjectParser` because I don't think it is worth it right now.
As the translog evolves towards a full operations log as part of the
sequence numbers push, there is a need for the translog to be able to
represent operations for which a sequence number was assigned, but the
operation did not mutate the index. Examples of how this can arise are
operations that fail after the sequence number is assigned, and gaps in
this history that arise when an operation is assigned a sequence number
but the operation never completed (e.g., a node crash). It is important
that these operations appear in the history so that they can be
replicated and replayed during recovery as otherwise the history will be
incomplete and local checkpoints will not be able to advance. This
commit introduces a no-op to the translog to set the stage for these
efforts.

Introduces `XContentParser#namedObject which works a little like
`StreamInput#readNamedWriteable`: on startup components register
parsers under names and a superclass. At runtime we look up the
parser and call it to parse the object.
Right now the parsers take a context object they use to help with
the parsing but I hope to be able to eliminate the need for this
context as most what it is used for at this point is to move
around parser registries which should be replaced by this method
eventually. I make no effort to do so in this PR because it is
big enough already. This is meant to the a start down a road that
allows us to remove classes like `QueryParseContext`,
`AggregatorParsers`, `IndicesQueriesRegistry`, and
`ParseFieldRegistry`.
The goal here is to reduce the amount of plumbing required to
allow parsing pluggable things. With this you don't have to pass
registries all over the place. Instead you must pass a super
registry to fewer places and use it to wrap the reader. This is
the same tradeoff that we use for NamedWriteable and it allows
much, much simpler binary serialization. We think we want that
same thing for xcontent serialization.
The only parsing actually converted to this method is parsing
`ScoreFunctions` inside of `FunctionScoreQuery`. I chose this
because it is relatively self contained.
It looks like the exception reason can differ in different default
locales, so the build would fail in any non-English locale. This
switches the catch to the name of the exception which shouldn't
vary.
Moves the last of the "easy" parser construction into
`RestRequest`, this time with a new method
`RestRequest#contentParser`. The rest of the production
code that builds `XContentParser` isn't "easy" because it is
exposed in the Transport Client API (a Builder) object.
To get #22003 in cleanly we need to centralize as much `XContentParser` creation as possible into `RestRequest`. That'll mean we have to plumb the `NamedXContentRegistry` into fewer places.
This removes `RestAction.hasBody`, `RestAction.guessBodyContentType`, and `RestActions.getRestContent`, moving callers over to `RestRequest.hasContentOrSourceParam`, `RestRequest.contentOrSourceParam`, and `RestRequest.contentOrSourceParamParser` and `RestRequest.withContentOrSourceParamParserOrNull`. The idea is to use `withContentOrSourceParamParserOrNull` if you need to handle requests without any sort of body content and to use `contentOrSourceParamParser` otherwise.
I believe the vast majority of this PR to be purely mechanical but I know I've made the following behavioral change (I'll add more if I think of more):
* If you make a request to an endpoint that requires a request body and has cut over to the new APIs instead of getting `Failed to derive xcontent` you'll get `Body required`.
* Template parsing is now non-strict by default. This is important because we need to be able to deprecate things without requests failing.
If you try to close the rest client inside one of its callbacks then
it blocks itself. The thread pool switches the status to one that
requests a shutdown and then waits for the pool to shutdown. When
another thread attempts to honor the shutdown request it waits
for all the threads in the pool to finish what they are working on.
Thus thread a is waiting on thread b while thread b is waiting
on thread a. It isn't quite that simple, but it is close.

This is an attempt to start moving aggs parsing to `ObjectParser`. There is
still A LOT to do, but ObjectParser is way better than the way aggregations
parsing works today. For instance in most cases, we reject numbers that are
provided as strings, which we are supposed to accept since some client languages
(looking at you Perl) cannot make sure to use the appropriate types.

* Remove 2.0 prerelease version constants
This is a start to addressing #21887. This removes:
* pre 2.0 snapshot format support
* automatic units addition to cluster settings
* bwc check for delete by query in pre 2.0 indexes
`_update_by_query` supports specifying the `pipeline` to process the
documents as a url parameter but `_reindex` doesn't. It doesn't because
everything about the `_reindex` request that has to do with writing
the documents is grouped under the `dest` object in the request body.
This changes the response parameter from
`request [_reindex] contains unrecognized parameter: [pipeline]` to
`_reindex doesn't support [pipeline] as a query parmaeter. Specify it in the [dest] object instead.`
Action filters currently have the ability to filter both the request and
response. But the response side was not actually used. This change
removes support for filtering responses with action filters.
Changes the default socket and connection timeouts for the rest
client from 10 seconds to the more generous 30 seconds.
Defaults reindex-from-remote to those timeouts and make the
timeouts configurable like so:
```
POST _reindex
{
"source": {
"remote": {
"host": "http://otherhost:9200",
"socket_timeout": "1m",
"connect_timeout": "10s"
},
"index": "source",
"query": {
"match": {
"test": "data"
}
}
},
"dest": {
"index": "dest"
}
}
```
Closes#21707
For the record, I also had to remove the geo-hash cell and geo-distance range
queries to make the code compile. These queries already throw an exception in
all cases with 5.x indices, so that does not hurt any more.
I also had to rename all 2.x bwc indices from `index-${version}` to
`unsupported-${version}` to make `OldIndexBackwardCompatibilityIT`
happy.
Today when handling unreleased versions for backwards compatilibity
support, we scatted version constants across the code base and add some
asserts to support removing these constants when the version in question
is actually released. This commit improves this situation, enabling us
to just add a single unreleased version constant that can be renamed
when the version is actually released. This should make maintenance of
these versions simpler.

* Scripting: Remove groovy scripting language
Groovy was deprecated in 5.0. This change removes it, along with the
legacy default language infrastructure in scripting.
This commit exposes the executor service interface from thread
pool. This will enable some high-level concurrency primitives that will
make some code cleaner and simpler.

We kept `netty_3` as a fallback in the 5.x series but now that master
is 6.0 we don't need this or in other words all issues coming up with
netty 4 will be blockers for 6.0.

In the test for reindex and friend's rethrottling feature we were waiting
only for a single reindex sub task to start before rethrottling. This
mostly worked because starting tasks is fast. But it didn't *always work
and CI found that for us. This fixes the test to wait for all subtasks
to start before rethrottling.
I reproduced this locally semi-consistently with some fairly creative
`Thread.sleep` calls and this test fix fixes the issue even with the
sleeps so I'm fairly sure this will work consistently.
Closes#21446
The method used to be called `isSourceEmpty`, and was renamed to `hasSource`, but the return value never changed. Updated tests and users accordingly.
Closes#21419
If you try to reindex with multiple slices against a node that
doesn't support it we throw an `IllegalArgumentException` so
`assertVersionSerializable` is ok with it and so if this happens
in REST it comes back as a 400 error.
