For the refactoring of SortBuilders related to #10217, each SortBuilder needs to get a build()
method that produces a SortField according to the SortBuilder parameters on the shard.
This commit fixes string formatting issues in the error handling and
provides a bettter error message if malformed input is detected.
This commit also adds tests for both situations.
Relates to #17212
this is the last step to remove node level service from IndexShard.
This means that tests can now more easily create an IndexShard instance
without starting a node and removes the dependency between IndexShard and Client/ScriptService
When a master is elected, it reaches out to all master nodes for their cluster state, selecting the one with the highest version. At the moment, we do another round to select the index metadata with the highest version as well. This is not needed - the election of a cluster state is enough - we should just use whatever indices are in it.
Closes#17233
We can do better than just throwing an error when we don't find a
setting. It's actually trivial to leverage lucenes slow LD StringDistance
to find possible candiates for a setting to detect missspellings and suggest
a possible setting.
This commit adds error messages like:
* `unknown setting [index.numbe_of_replica] did you mean [index.number_of_replicas]?`
rather than just reporting the setting as unknown
Today if something is wrong with the IndexMetaData we detect it very
late and most of the time if that happens we already allocated the index
and get endless loops and full log files on data-nodes. This change tries
to verify IndexService creattion during initial state recovery on the master
and if the recovery fails the index is imported as `closed` and won't be allocated
at all.
Closes#17187
In 5.0 we don't allow index settings to be specified on the node level ie.
in yaml files or via commandline argument. This can cause problems during
upgrade if this was used extensively. For instance if analyzers where
specified on a node level this might cause the index to be closed when
imported (see #17187). In such a case all indices relying on this
must be updated via `PUT /${index}/_settings`. Yet, this API has slightly
different semantics since it overrides existing settings. To make this less
painful this change adds a `preserve_existing` parameter on that API to ensure
we have the same semantics as if the setting was applied on the node level.
This change also adds a better error message and a change to the migration guide
to ensure upgrades are smooth if index settings are specified on the node level.
If a index setting is detected this change fails the node startup and prints a message
like this:
```
*************************************************************************************
Found index level settings on node level configuration.
Since elasticsearch 5.x index level settings can NOT be set on the nodes
configuration like the elasticsearch.yaml, in system properties or command line
arguments.In order to upgrade all indices the settings must be updated via the
/${index}/_settings API. Unless all settings are dynamic all indices must be closed
in order to apply the upgradeIndices created in the future should use index templates
to set default values.
Please ensure all required values are updated on all indices by executing:
curl -XPUT 'http://localhost:9200/_all/_settings?preserve_existing=true' -d '{
"index.number_of_shards" : "1",
"index.query.default_field" : "main_field",
"index.translog.durability" : "async",
"index.ttl.disable_purge" : "true"
}'

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
During the aggregation refactoring the default value for `keyed` in the `percentiles` and `percentile_ranks` aggregation was inadvertently changed from `true` to `false`. This change reverts the defaults to the old (correct) value
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:
Closes#10741Closes#7297Closes#13176Closes#13978Closes#11264Closes#10741Closes#4317
Also adding checks for median SortMode on non-numeric field types
to FieldSortBuilder, removing some unused code and switching
GeoDistanceSortBuilder to using ParseField.
Provide better error message when an incompatible node connects to a node
We should give a better exception message when an incompatible node connects
and we receive a messeage. This commit adds a clear excpetion based on the
protocol version received instead of throwing cryptic messages about not fully reaed
buffer etc.

The previous method sorted first by _score, then _uid. In certain situations, this allowed
floating point errors to slightly alter the sort order, causing test failure.
We only sort on _uid now, which should be deterministic and allow comparison of ten
documents. Not quite as useful, but less fragile and we still check to make sure num hits
and max score are identical.
Closes#17164
If this query doesn't take the child type into account then it can match other
child document types pointing to the same parent type and that have the same id too.
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
This commit fixes an OOM error that happens when the XContentParser.readList() method is asked to parse a single value instead of an array. It fixes the UpdateRequest parsing as well as remove some leniency in the readList() method so that it expect to be in an array before parsing values.
closes#15338
Now we have 16870 we can enable the request cache by default. The caching can still be disabled on a per request basis and can still be disabled in the settings, only the default value has changed. For now this is done regardless of whether the shard is active or inactive.
Closes#17134
This change adds a rewrite phase to the queries on the shard before they are assessed for caching or executed. This allows the opportunity to rewrite queries as faster running simpler queries based on attributes known to only the shard itself. The first query to implement this is the RangeQueryBuilder which will rewrite to a MatchAllQueryBuilder if the range of terms on the shard is a subset of the query and rewrites to a MatchNoneQueryBuilder if the range of terms on the shard is completely outside the query.
