The fielddata settings in mappings have been refatored so that:
- text and string have a `fielddata` (boolean) setting that tells whether it
is ok to load in-memory fielddata. It is true by default for now but the
plan is to make it default to false for text fields.
- text and string have a `fielddata_frequency_filter` which contains the same
thing as `fielddata.filter.frequency` used to (but validated at parsing time
instead of being unchecked settings)
- regex fielddata filtering is not supported anymore and will be dropped from
mappings automatically on upgrade.
- text, string and _parent fields have an `eager_global_ordinals` (boolean)
setting that tells whether to load global ordinals eagerly on refresh.
- in-memory fielddata is not supported on keyword fields anymore at all.
- the `fielddata` setting is not supported on other fields that text and string
and will be dropped when upgrading if specified.
Currently, both Gsub and Grok parse regex strings during
Pipeline creation. Thrown parsing exceptions were leaking out, this
commit wraps those exceptions in ElasticsearchParseExceptions.
We current have a ClusterService interface, implemented by InternalClusterService and a couple of test classes. Since the decoupling of the transport service and the cluster service, one can construct a ClusterService fairly easily, so we don't need this extra indirection.
Closes#17183
Also replaced the PercolatorQueryRegistry with the new PercolatorQueryCache.
The PercolatorFieldMapper stores the rewritten form of each percolator query's xcontext
in a binary doc values field. This make sure that the query rewrite happens only during
indexing (some queries for example fetch shapes, terms in remote indices) and
the speed up the loading of the queries in the percolator query cache.
Because the percolator now works inside the search infrastructure a number of features
(sorting fields, pagination, fetch features) are available out of the box.
The following feature requests are automatically implemented via this refactoring:

Today we allow to set all kinds of index level settings on the node level which
is error prone and difficult to get right in a consistent manner.
For instance if some analyzers are setup in a yaml config file some nodes might
not have these analyzers and then index creation fails.
Nevertheless, this change allows some selected settings to be specified on a node level
for instance:
* `index.codec` which is used in a hot/cold node architecture and it's value is really per node or per index
* `index.store.fs.fs_lock` which is also dependent on the filesystem a node uses
All other index level setting must be specified on the index level. For existing clusters the index must be closed
and all settings must be updated via the API on each of the indices.
Closes#16799
Without this commit fetching the status of a reindex from a node that isn't
coordinating the reindex will fail. This commit properly registers reindex's
status so this doesn't happen. To do so it moves all task status registration
into NetworkModule and creates a method to register other statuses which the
reindex plugin calls.
The build currently uses the old maven support in gradle. This commit
switches to use the newer maven-publish plugin. This will allow future
changes, for example, easily publishing to artifactory.
An additional part of this change makes publishing of build-tools part
of the normal publishing, instead of requiring a separate upload step
from within buildSrc. That also sets us up for a follow up to enable
precomit checks on the buildSrc code itself.
Add infrastructure to run REST tests on a multi-version cluster
This change adds the infrastructure to run the rest tests on a multi-node
cluster that users 2 different minor versions of elasticsearch. It doesn't implement
any dedicated BWC tests but rather leverages the existing REST tests.
Since we don't have a real version to test against, the tests uses the current version
until the first minor / RC is released to ensure the infrastructure works.
Given the amount of problems this change already found I think it's worth having this run with our test suite by default. The structure of this infra will likely change over time but for now it's a step into the right direction. We will likely want to split it up into integTests and integBwcTests etc. so each plugin can have it's own bwc tests but that's left for future refactoring.
Today index names are often resolved lazily, only when they are really
needed. This can be problematic especially when it gets to mapping updates
etc. when a node sends a mapping update to the master but while the request
is in-flight the index changes for whatever reason we would still apply the update
since we use the name of the index to identify the index in the clusterstate.
The problem is that index names can be reused which happens in practice and sometimes
even in a automated way rendering this problem as realistic.
In this change we resolve the index including it's UUID as early as possible in places
where changes to the clusterstate are possible. For instance mapping updates on a node use a
concrete index rather than it's name and the master will fail the mapping update iff
the index can't be found by it's <name, uuid> tuple.
Closes#17048
Today, certain bootstrap properties are set and read via system
properties. This action-at-distance way of managing these properties is
rather confusing, and completely unnecessary. But another problem exists
with setting these as system properties. Namely, these system properties
are interpreted as Elasticsearch settings, not all of which are
registered. This leads to Elasticsearch failing to startup if any of
these special properties are set. Instead, these properties should be
kept as local as possible, and passed around as method parameters where
needed. This eliminates the action-at-distance way of handling these
properties, and eliminates the need to register these non-setting
properties. This commit does exactly that.
Additionally, today we use the "-D" command line flag to set the
properties, but this is confusing because "-D" is a special flag to the
JVM for setting system properties. This creates confusion because some
"-D" properties should be passed via arguments to the JVM (so via
ES_JAVA_OPTS), and some should be passed as arguments to
Elasticsearch. This commit changes the "-D" flag for Elasticsearch
settings to "-E".
This change adds the infrastructure to run the rest tests on a multi-node
cluster that users 2 different minor versions of elasticsearch. It doesn't implement
any dedicated BWC tests but rather leverages the existing REST tests.
Since we don't have a real version to test against, the tests uses the current version
until the first minor / RC is released to ensure the infrastructure works.

The refresh tests were failing rarely due to refreshes happening
automatically on indexes with -1 refresh intervals. This commit moves
the refresh test into a unit test where we can check if it was attempted
so we never get false failures from background refreshes.
It also stopped refresh from being run if the reindex request was canceled.
Indexing failures have caused the reindex http request to fail for a while
now. Both search and indexing failures cause it to abort. But search
failures didn't cause a non-200 response code from the http api. This
fixes that.
Also slips in a fix to some infrequently failing rest tests.
Closes#16037
Implements CompositeIndicesRequest on UpdateByQueryRequest and
ReindexRequest so that plugins can reason about the request. In both cases
this implementation is imperfect but useful because instead of listing
all requests that make up the request it instead attempts to make dummy
requests that represent the requests that it will later make.
Use index UUID to lookup indices on IndicesService
Today we use the index name to lookup index instances on the IndicesService
which applied to search requests but also to index deletion etc. This commit
moves the interface to expect an Index instance which is a tuple
and looks up the index by uuid rather than by name. This prevents accidental modification
of the wrong index if and index is recreated or searching from the wrong index in such a case.
Accessing an index that has the same name but different UUID will now result in an IndexNotFoundException.

_wait_for_completion defaults to false. If set to true then the API will
wait for all the tasks that it finds to stop running before returning. You
can use the timeout parameter to prevent it from waiting forever. If you
don't set a timeout parameter it'll default to 30 seconds.
Also adds a log message to rest tests if any tasks overrun the test. This
is just a log (instead of failing the test) because lots of tasks are run
by the cluster on its own and they shouldn't cause the test to fail. Things
like fetching disk usage from the other nodes, for example.
Switches the request to getter/setter style methods as we're going that
way in the Elasticsearch code base. Reindex is all getter/setter style.

update to lucene 6 jars
No changes were really needed in our test infra as it didn't use `node.client`. Yet it didn't take into account ingest nodes, what we used to call client nodes in InternalTestCluster were actually ingest only nodes, which now become coordinating only nodes.
Also renamed some method to get rid of the node client terminology as much as possible in favour or coordinating only node.
The field name is a required argument for all suggesters, but
it was specified via a field() setter in SuggestionBuilder so far.
This changes field name to being a mandatory constructor argument
and lets suggestion builders throw an error if field name is missing
or the empty string.
This commit removes the ability to use string fields on indices created on or
after 5.0. Dynamic mappings now generate text fields by default for strings
but there are plans to also add a sub keyword field (in a future PR).
Most of the changes in this commit are just about replacing string with
keyword or text. Some tests have been removed because they existed because of
corner cases of string mappings like setting ignore-above on a text field or
enabling term vectors on a keyword field which are now impossible.
The plan is to remove strings entirely in 6.0.
Currently each suggestion keeps track of its own name. This has
the disadvantage of having to pass down the parsed name property
in the suggestions fromXContent() and the serialization methods
as an argument, since we need it in the ctor.
This change moves the naming of the suggestions to the surrounding
SuggestBuilder and by this eliminates the need for passind down
the names in the parsing and serialization methods. By making
`name` a required argument in SuggestBuilder#addSuggestion() we
also make sure it is always set and prevent using the same name twice,
which wasn't possible before.
The suffix TransportAction is misleading as it may make think that it extends TransportAction, but it does not. This class makes accessible the different search operations exposed by SearchService through the transport layer. Also resolved few compiler warnings in the class itself.
Also renamed histogram.AbstractBuilcer to AbstractHistogramBuilder, range.AbstractBuilder to AbstractRangeBuilder and org.elasticsearch.search.aggregations.pipeline.having to org.elasticsearch.search.aggregations.pipeline.bucketselector
The `keyword` field is intended to replace `not_analyzed` string fields. It is
indexed and has doc values by default, and doesn't support enabling term
vectors.
Although it doesn't support setting an analyzer for now, there are plans for
it to support basic normalization in the future such as case folding.
QueryBuilders today do all their heavy lifting in toQuery() which
can be too late for several operations. For instance if we want to fetch geo shapes
on the coordinating node we need to do all this before we create the actual lucene query
which happens on the shard itself. Also optimizations for request caching need to be done
to the query builder rather than the query which then in-turn needs to be serialized again.
This commit adds the basic infrastructure for query rewriting and moves the heavy lifting into
the rewrite method for the following queries:
* `WrapperQueryBuilder`
* `GeoShapeQueryBuilder`
* `TermsQueryBuilder`
* `TemplateQueryBuilder`
Other queries like `MoreLikeThisQueryBuilder` still need to be fixed / converted. The nice
sideeffect of this is that queries like template queries will now also match the request cache
if their non-template equivalent has been cached befoore. In the future this will allow to
add optimizataion like rewriting time-based queries into primitives like `match_all_docs` or `match_no_docs`
based on the currents shards bounds. This is especially appealing for indices that are read-only ie. never change.
