The rangeQuery() method in MappedFieldType and some overwriting subtypes takes
a nullable QueryParseContext argument which is unused and can be deleted.
This is also useful for the current query parsing refactoring, since
we want to avoid passing the context object around unnecessarily.
IndicesStoreIntegrationTests.indexCleanup() tests if the shard files on disk are actually removed
after relocation. In particular it tests the following:
Whenever a node deletes a shard because it was relocated somewhere else, it first
checks if enough other copies are started somewhere else. The node sends a
ShardActiveRequest to the nodes that should have a copy.
The nodes that receive this request check if the shard is in state STARTED in which case
they respond with true. If they have the shard in POST_RECOVERY they register a cluster state
observer that checks at each update if the shard has moved to STARTED and respond with true when
this happens.
To test that the cluster state observer mechanism actually works, the latter can be triggered by
blocking the cluster state processing when a recover starts and only unblocking it shortly
after the node receives the ShardActiveRequest.
This is more reliable than using random cluster state processing delays
because the random delays make it hard to reason about different timeouts
that can be reached.

Ignore EngineClosedException during translog fysnc
When performing an operation on a primary, the state is captured and the
operation is performed on the primary shard. The original request is
then modified to increment the version of the operation as preparation
for it to be sent to the replicas.
If the request first fails on the primary during the translog sync
(because the Engine is already closed due to shadow primaries closing
the engine on relocation), then the operation is retried on the new primary
after being modified for the replica shards. It will then fail due to the
version being incorrect (the document does not yet exist but the request
expects a version of "1").
Order of operations:
- Request is executed against primary
- Request is modified (version incremented) so it can be sent to replicas
- Engine's translog is fsync'd if necessary (failing, and throwing an exception)
- Modified request is retried against new primary
This change ignores the exception where the engine is already closed
when syncing the translog (similar to how we ignore exceptions when
refreshing the shard if the ?refresh=true flag is used).

Correctly list blobs in Azure storage to prevent snapshot corruption and do not unnecessarily duplicate Lucene segments in Azure Storage
This commit addresses an issue that was leading to snapshot corruption for snapshots stored as blobs in Azure Storage.
The underlying issue is that in cases when multiple snapshots of an index were taken and persisted into Azure Storage, snapshots subsequent
to the first would repeatedly overwrite the snapshot files. This issue does render useless all snapshots except the final snapshot.
The root cause of this is due to String concatenation involving null. In particular, to list all of the blobs in a snapshot directory in
Azure the code would use the method listBlobsByPrefix where the prefix is null. In the listBlobsByPrefix method, the path keyPath + prefix
is constructed. However, per 5.1.11, 5.4 and 15.18.1 of the Java Language Specification, the reference null is first converted to the string
"null" before performing the concatenation. This leads to no blobs being returned and therefore the snapshot mechanism would operate as if
it were writing the first snapshot of the index. The fix is simply to check if prefix is null and handle the concatenation accordingly.
Upon fixing this issue so that subsequent snapshots would no longer overwrite earlier snapshots, it was discovered that the snapshot metadata
returned by the listBlobsByPrefix method was not sufficient for the snapshot layer to detect whether or not the Lucene segments had already
been copied to the Azure storage layer in an earlier snapshot. This led the snapshot layer to unnecessarily duplicate these Lucene segments
in Azure Storage.
The root cause of this is due to known behavior in the CloudBlobContainer.getBlockBlobReference method in the Azure API. Namely, this method
does not fetch blob attributes from Azure. As such, the lengths of all the blobs appeared to the snapshot layer to be of length zero and
therefore they would compare as not equal to any new blobs that the snapshot layer is going to persist. To remediate this, the method
CloudBlockBlob.downloadAttributes must be invoked. This will fetch the attributes from Azure Storage so that a proper comparison of the
blobs can be performed.

In addition documentation has been updated as well, where it was

This dependency was used in order for mapping updates that change the fielddata
format to take effect immediately. And the way it worked was by clearing the
cache of fielddata instances that were already loaded. However, we do not need
to cache the already loaded (logical) fielddata instances, they are cheap to
regenerate. Note that the fielddata _caches_ are still kept around so that we
don't keep on rebuilding costly (physical) fielddata values.

The `_index` field is now a completely virtual field thanks
to #12027. It is no longer necessary to index the actual value
of the index name.
closes#12329
The index name was passed along through many levels of mapping parsing,
just so that it could be used for _index. However, the index name
is really metadata that should exist alongside things like type and
id in SourceToParse.
This change moves index name to SourceToParse, and eliminates it from the
DocumentMapperParser.
Today we grant read+write+delete access to any files underneath the home.
But we have to remove this, if we want to have improved security of files
underneath elasticsearch.
Fold ignored unassigned to a UnassignedShards and have simpler handling of them. Also remove the trapy way of adding an ignored unassigned shards today directly to the list, and have dedicated methods for it.
This change also removes the useless moving of unassigned shards to the end, since anyhow we first, sort those unassigned shards, and second, we now have persistent "store exceptions" that should not cause "dead letter" shard allocation.
Break it into more manageable code by separating allocation primaries and allocating replicas. Start adding basic unit tests for primary shard allocator.
Our thread pools have support for timeout on a task. To support this, a special background task is schedule to run at timeout. That background task fires and check if the main task is still in the executor queue and then cancels it if needed. Currently we schedule this background task before adding the main task to the queue. If the timeout is very small (in tests we often use numbers like 2 ms) the background task can fire before the main one is added to the queue causing the timeout to be missed.
See http://build-us-00.elastic.co/job/es_g1gc_master_metal/11780/testReport/junit/org.elasticsearch.cluster/ClusterServiceTests/testTimeoutUpdateTask/Closes#12319
On top of that:
1) A relocation target shards' allocation id is changed to include the allocation id of the source shard under relocatingId (similar to shard routing semantics)
2) The logic around state change for finalize shard relocation is simplified - one simple start the target shard (we previously had unused logic around relocating state)
Closes#12299
While the GeoJSON spec does say a polygon is represented as an array of LinearRings (where a LinearRing is defined as a 'closed' array of points), the coerce parameter provides users with flexibility to have ES automatically close polygons. This addresses situations like those integrated with twitter (where GeoJSON polygons are not closed) such that our users do not have to write extra code to close the polygon. This code change adds the optional coerce parameter to the GeoShapeFieldMapper.

Currently this target is "yet another way" to run elasticsearch,
which we can't maintain. It also has the problem that it doesnt
ensure its running on the latest source code, doesn't configure
any scratch space properly, won't work with securitymanager, list
goes on.
Even if we made it work, it would break every day, since its untested.
Instead, `mvn package -Drun -DskipTests` will run packaging, and then
startup bin/elasticsearch (like integration tests, but in foreground).
It also enables debugger socket on port 8000, for people that like
IDE debuggers and not system.out.println.
Its a little slower to get started because of all the shading/RPM/DEB
building going on in `package` but that is just what it is right now
until that stuff is moved out.
failsafe uses surefire, which sucks. It also mean integ tests act alien right now.
I would rather have the consistency, e.g. things formatted the same way, running integ tests under security manager, etc.

When adding a script to the Groovy classloader, the script name is used
as the class identifier in the classloader. This means that in order not
to break JVM Classloader convention, that script must always be
available by that name. As a result, modifying a script with the same
content over and over causes it to be loaded with a different name (due
to the incrementing integer).
This is particularly bad when something like chef or puppet replaces the
on-disk script file with the same content over and over every time a
machine is converged.
This change makes the script name the SHA1 hash of the script itself,
meaning that replacing a script with the same text will use the same
script name.

Most of our tests call assertSearchResponse which checks whether all shards
were successful. However this is usually not necessary given that all shards
that received documents should be available given the way our indexing works.
The only shards that might not be available are those that did not index
any documents. So removing this assertion would allow us to remove most
ensureGreen/ensureYellow calls while still being able to assert on the content
of the search response since all data have been taken into account.
For now I only removed the ensureYellow/Green calls from SearchQueryTests in
order to not de-stabilize the build, but eventually we should remove most of
them.
Today, the unicast zen test configuration will try to find a open port starting at the internal test cluster's
base port and continuing for 1000 ports. The internal test cluster class assigns a port range of 100 ports
to each JVM. This means that the unicast zen test configuration will try ports in the range for another JVM
and can lead to port conflicts. This change uses the same value for both so that the unicast configuration
does not go into another JVM's port range.
Add a unique allocation id for a shard, helping to uniquely identify a specific allocation taking place to a node.
A special case is relocation, where a transient relocationId is kept around to make sure the target initializing shard (when using RoutingNodes) is using it for its id, and when relocation is done, the transient relocationId becomes the actual id of it.
closes#12242
If an index name is reused but a leftover shard still exists on any node
we fail repeatedly to allocate the shard since we now check the index UUID
before reusing data. This commit allows to recover even if there is such a
leftover shard by deleting the leftover shard.

During master election each node pings in order to discover other nodes and validate the liveness of existing nodes. Based on this information the node either discovers an existing master or, if enough nodes are found (based on `discovery.zen.minimum_master_nodes>>) a new master will be elected.
Currently, the node that is elected as master will currently update it the cluster state to indicate the result of the election. Other nodes will submit a join request to the newly elected master node. Instead of immediately processing the election result, the elected master
node should wait for the incoming joins from other nodes, thus validating the elections result is properly applied. As soon as enough nodes have sent their joins request (based on the `minimum_master_nodes` settings) the cluster state is modified.
Note that if `minimum_master_nodes` is not set, this change has no effect.
Closes#12161

The old script syntax has been removed from the Java API but the metrics aggregations were missed. This change removes the old script API from the ValuesSourceMetricsAggregationBuilder and removes the relevant test methods for the metrics aggregations.
Today we have a intermediate hierarchy for shard and index exceptions
which makes it hard to introduce generic exceptions like ResourceNotFoundException
intoduced in this commit. This commit breaks up the hierarchy by adding index and shard
as a special internal header that gets rendered for every exception that fills that header.
This commit removes dedicated exceptions like `IndexMissingException` or
`IndexShardMissingException` in favour of `ResourceNotFoundException`
Change the default delayed allocation timeout from 0 (no delayed allocation) to 1m. The value came from a test of having a node with 50 shards being indexed into (so beefy translog requiring flush on shutdown), then shutting it down and starting it back up and waiting for it to join the cluster. This took, on a slow machine, about 30s.
The value is conservatively low and does not try to address a virtual machine / OS restart for now, in order to not have the affect of node going away and users being concerned that shards are not being allocated to the rest of the cluster as a result of that. The setting can always be changed in order to increase the delayed allocation if needed.

The MetaData.clusterUUID is guaranteed to be unique across clusters and is handy (which may or may not have the same human readable cluster name).
Closes#11832
As explained in #11831, we currently have uuid fields on the cluster state, meta data and index metadata. The latter two are persistent across changes are being effectively used as a persistent uuid for this cluster and a persistent uuid for an index. The first (ClusterState.uuid) is ephemeral and changes with every change to the cluster state. This is confusing,
We settled on having the following, new names:
-> ClusterState.uuid -> stateUUID (transient)
-> MetaData.uuid -> clusterUUID (persistent)
-> IndexMetaData.uuid -> indexUUID (persistent).
Closes#11914Closes#11831
Today we throw ElasticsearchException if we can't lock the index. This can cause
problems since some places where we have logic to deal with IOException on shard
deletion won't schedule a retry if we can't lock the index dir for removal. This
is the case on shadow replicas for instance if a shared FS is used. The result
of this is that the delete of an index is never acked.
A change in #12116 introduces closing / cleaning of search ctx even if
the index service was closed due to a relocation of it's last shard. This
is not desired since in that case it's fine to serve the pending requests from
the relocated shard. This commit adds an extra check to ensure that the index is
either removed (delete) or closed via API.
The term query parser was too lenient during parsing and allowed to specify
more than one field, even though this expected to filter only for a single field.
This commit returns an exception if a query has been specified more than once.

with newly added name and type member variables.
This can in turn be used to give better scripting error messages
with the type of script used and the name of the script.
Required slight modifications to the caching mechanism.
Note that this does not enforce good behavior in that plugins will
have to write exceptions that also output the name of the script
in order to be effective. There was no way to wrap the script
methods in a try/catch block properly further up the chain because
many have script-like objects passed back that can be run at a
later time.

Changes in a nutshell:
* All expression logic is now encapsulated by ExpressionResolver interface.
* MetaData#convertFromWildcards() gets replaced by WildcardExpressionResolver.
* All of the indices expansion methods are being moved from MetaData class to the new IndexNameExpressionResolver class.
* All single index expansion optimisations are removed.
The logic for resolving a concrete index name from an expression has been moved from MetaData to IndexExpressionResolver. The logic has been cleaned up and simplified were was possible without breaking bwc.
Also the notion of aliasOrIndex has been changed to index expression.
The IndexNameExpressionResolver translates index name expressions into concrete indices. The list of index name expressions are first delegated to the known ExpressionResolverS. An ExpressionResolver is responsible for translating if possible an expression into another expression (possibly but not required this can be concrete indices or aliases) otherwise the expressions are left untouched. Concretely this means converting wildcard expressions into concrete indices or aliases, but in the future other implementations could convert expressions based on different rules.
To prevent many overloading of methods, DocumentRequest extends now from IndicesRequest. All implementation of DocumentRequest already did implement IndicesRequest indirectly.
This allows the creation of the RPM artifact as part of the
maven package phase. The result of this is that we get checksum and
name correction for-free as it's all build an installed into the m2
repository. This also publishes the RPM together with .deb to the mvn
mirror.
Note: this will only build the RPM as part of the package phase if
`-Dpackage.rpm=true` since the binaries to build the RPM are not
availabel on all platforms.
Today we only clear search contexts for deleted indies. Yet, we should
do the same for closed indices to ensure they can be reopened quickly.
Closes#12116
A method for the new Script API were missing in the ValuesSourceMetricsAggregationBuilder. This change adds the missing method and deprecates the old Script API methods
When a node sends a shard started message to the master, the master goes through the routing table looking for the shard to start. At the moment we validate the indexUUID, the node the shard is assigned to and the fact that the shard is initializing. This check goes wrong if a relocating replica shard finishes recovery just at the moment the source node leaves the cluster. In this case the master will cancel the recovery and will likely assign a new initializing replica to the same target node. In this case the message from the relocation recovery can activate the new replica wrongfully.
Also, the logic for decided whether an incoming shard started message will be applied was split between ShardStateAction and the AllocationService.
This commit does the following:
1) Let ShardStateAction only filter basic stuff like index existence and indexUUID.
2) Move the trickier shard started matching logic to the AllocationService and make it stricter
3) Unify ShardStateAction filtering logic for both shard started and shard failed.
4) Add unit tests for all of the above.

Today everything is tight to having the next version as the latest.
In order to work towards 2.0.0.beta1 we need to fix all the usage of
2.0.0-SNAPSHOT to reflect the version we will release soon.
Usually we do this on the release branch but to simplify things I wanna
keep this on master for now and move to 2.1.0-SNAPSHOT on master once
we created a 2.0 branch.
Closes#12148
This information was stored with the snapshot but wasn't available on the interface. Knowing the version of elasticsearch that created the snapshot can be useful to determine the minimal version of the cluster that is required in order to restore this snapshot.
Closes#11980
This change fixes the plugin manager to trim `elasticsearch-` and `es-` prefixes from plugin names
for our official plugins. This restores the old behavior prior to #11805.
Closes#12143
Today it will remove all permissions and only set execute bit:
---x--x--x
Instead we should preserve existing permissions, and just add
read and execute to whatever is there.
Closes#12142
This change allows custom settings to be passed to the client for the external test cluster,
which is necessary when additional settings need to be passed to the client in order to
properly communicate with the external test cluster.
Before inner_hits existed named queries has support to also verify if inner queries of nested query matched with returned documents. This logic was broken and became obsolete from the moment inner hits get released. #10694 fixed named queries for nested docs in the top_hits agg, but it didn't fix the named query support for nested inner hits. This commit fixes that and on top of this also adds support for parent/child inner hits.
We allow setting the node's name a few different ways: the `name` system
property, the setting `name`, and the setting `node.name`. There is an order
of preference to these settings that gets applied, which can copy values from the
system property or `node.name` setting to the `name` setting. When setting
only `node.name` to one of the prompt placeholders, the user would be
prompted twice as the value of `node.name` is copied to `name` prior to
prompting for input. Additionally, the value entered by the user for `node.name`
would not be used and only the value entered for `name` would be used.
This fix changes the behavior to only prompt once when `node.name is set` and
`name` is not set. This is accomplished by waiting until all values have been
prompted and replaced, then the logic for determining the node's name is
executed.
Closes#11564
This commit adds support to retrieve fields when using the bulk update API. This functionality was previously available for the update API
but not for the bulk update API.
Closes#11527
Fixed documentation since the default rewrite method for fuzzy queries is to
select top terms, fixed usage of the fuzzy rewrite method, and removed unused
`rewrite` parameter.
Close#6932
This rewrite method is interesting because it computes scores as if all terms
had the same frequencies, which avoids disappointments with ranking when a fuzzy
query ranks typos first given that they are less frequent than the correct term.
Today shards are responsible for producing one sort value per document, which
is later used on the coordinating node to resolve the global top documents.
However, this is problematic on string fields with
`missing: _first, order: desc` or `missing: _last, order: asc` given that there
is no such thing as a string that compares greater than any other string. Today
we use a string containing a single code point which is the maximum allowed code
point but this is a hack: instead we should inform the coordinating node that
the document had no value and let it figure out how it should be sorted
depending on whether missing values should be sorted first or last.
Close#9155
Simplify and consolidate ShardRouting construction. Make sure that there is really only one place it gets created, when a shard is first created in unassigned state, and from there on, it is either copy constructed or built internally as a target for relocation.
This change helps make sure within our codebase data carries over by the ShardRouting is not lost as the shard goes through transitions, and can help simplify the addition of more data on it (like uuid).
For testing, a centralized TestShardRouting allows to create testable versions of ShardRouting, that are not needed to be as strict as the non test codebase. This can be cleanup more later on, but it is a good start.
closes#12125
This makes FuzzyQueryBuilder and Parser take an Object as a value using the
same logic as termQuery, so that numbers, dates or Strings would be properly
handled.
Relates #11865Closes#12020
This converts the tracking of jars and classes in JarHell to use
Path objects, instead of URL. This makes for nicer printing
of the underlying path when an error does occur.
This commit defaults fuzzy_transpositions on fuzzy queries to true. This means that by default, tranpositions will now count as a single
edit.
Closes#9278
the failure type. This change marks the engine as corrupted only when the failure
is caused by an actual index corrruption. When an engine is failed for other
reasons, the engine is only closed without removing the shard state.
closes#11788
Plugin Manager can now use another simplified form when a user wants to install an official plugin hosted at elasticsearch download service.
The form we use is:
```sh
bin/plugin install pluginname
```
As plugins share now the same version as elasticsearch, we can automatically guess what is the exact current version of the plugin manager script.
Also, download service will now use `/org.elasticsearch.plugins/pluginName/pluginName-version.zip` URL path to download a plugin.
If the older form is provided (`user/plugin/version` or `user/plugin`), we will still use:
* elasticsearch download service at `/user/plugin/plugin-version.zip`
* maven central with groupIp=user, artifactId=plugin and version=version
* github with user=user, repoName=plugin and tag=version
* github with user=user, repoName=plugin and branch=master if no version is set
Note that community plugin providers can use other download services by using `--url` option.
If you try to use the new form with a non core elasticsearch plugin, the plugin manager will reject
it and will give you all known core plugins.
```
Usage:
-u, --url [plugin location] : Set exact URL to download the plugin from
-i, --install [plugin name] : Downloads and installs listed plugins [*]
-t, --timeout [duration] : Timeout setting: 30s, 1m, 1h... (infinite by default)
-r, --remove [plugin name] : Removes listed plugins
-l, --list : List installed plugins
-v, --verbose : Prints verbose messages
-s, --silent : Run in silent mode
-h, --help : Prints this help message
[*] Plugin name could be:
elasticsearch-plugin-name for Elasticsearch 2.0 Core plugin (download from download.elastic.co)
elasticsearch/plugin/version for elasticsearch commercial plugins (download from download.elastic.co)
groupId/artifactId/version for community plugins (download from maven central or oss sonatype)
username/repository for site plugins (download from github master)

AbstractFieldMapper is the only direct base class of FieldMapper.
This change moves all AbstractFieldMapper functionality into
FieldMapper, since there is no need for 2 levels of abstraction.
Each scroll on a scan causes a query to be executed. This commit adds support for these indirect queries to count against the search stats.
Additionally, this commit adds three new search stats: scroll_count, scroll_time_in_millis, and scroll_current. scroll_count tracks the
number of completed scrolls. scroll_time_in_millis tracks the total time that scrolls were held open. scroll_current tracks the number of
scrolls currently open.
Closes#9109
In testing infra, one can simulate node GCs, network issues and other problems by adding a disruption to the test cluster. Those disruption are automatically removed after the test is done. At the moment each disruption indicates how long it will take the cluster to heal once the disruption is removed and the test cluster waits for this amount of time. However, more often than not this is an upper bound, causing a much longer wait than needed. Instead we should push the responsibility of healing to the disruption it self, where we can be smarter about what we wait for.
Closes#12071
When using `awaitBusy`, sometimes, you might not want to double time between two runs in an infinitive manner.
For example, let's say it will probably take 30 seconds to run a test.
When doubling all the time, you will most likely wait for a bigger time than needed:

For example here, if the task is successful after 35 seconds, we will most likely have to wait for 32s more before the Predicate is run again.
With this patch, the maximum sleep time is now set to 1 second.
This pipeline aggregation runs a script on each bucket in the parent aggregation to determine whether the bucket is kept in the final aggregation tree. If the script returns true the bucket is retained, if it returns false the bucket is dropped
If you are using the default date or the named identifiers of dates,
the current implementation was allowed to read a year with only one
digit. In order to make this more strict, this fixes a year to be at
least 4 digits. Same applies for month, day, hour, minute, seconds.
Also the new default is `strictDateOptionalTime` for indices created
with Elasticsearch 2.0 or newer.
In addition a couple of not exposed date formats have been exposed, as they
have been mentioned in the documentation.
Closes#6158
Field names containing dots can cause problems. For example, @jpountz
made this recreation which cause no error, but can result in a
serialization exception if the type already exists:
https://gist.github.com/jpountz/8c66817e00a322b81f85
But this is not just a potential conflict. It also has larger problems,
since only the leaf mapper is created. The intermediate "foo" object
field would not exist if only "foo.bar" was in the mappings.
This change forbids the use of dots in field names. It also
fixes an issue with passing through the update_all_types setting,
which was always set to true whenever a type already existed (!).
I do not think we should worry about backwards compatibility here. This
should be a hard break (and added to the migration plugin).
This commit adds logic to prefer shards with higher priority
or from newer indicse to be allocated first if they are unallocated post API.
This commit allows users to set `index.priority` to a non-negative integer to
prioritize index recovery for certain indices. This setting is dynamically updateable
and defaults to `0`. If two indices have the same priority this change takes the creation
date into account to prioritize shards from newer indices which is important in the time-based
indices usecase.
Closes#11787
When a bulk request fails on a Delete or Update request, the BulkItemResponse
reports incorrect "index" operation in the response. This PR fixes this
for the case of closed indices as reported in #9821 but also for
other failures and adds tests for the two cases covered.
Closes#9821
the specialization can cause stack overflows if an exception is a
ElasticsearchWrapperException as well as a ElasticsearchException.
This commit just relies on the unwrap logic now to find the cause and only
renders if we the rendering exception is the cause otherwise forwards
to the generic exception rendering.
Closes#11994
While MappedFieldType contains settings for doc values and fielddata,
AbstractFieldMapper had special logic in its constructor that
required setting these on the field type from there. This change
removes those settings from the AbstractFieldMapper constructor.
As a result, defaultDocValues(), defaultFieldType() and
defaultFieldDataType() are no longer needed.
This commit merges the pre-existing special exception that
allowed to associate headers with exceptions and the elasticsaerch
base class `ElasticsearchException` This allows for more generic use
of exceptions where plugins can associate meta-data with any elasticsearch
base exception to control behavior etc.
This also addds a generic SecurityException to allow plugins to pass on
information based on the RestStatus.
If the version of a node is lower than the minimum supported version or higher than the maximum supported version, a node shouldn't be allowed to join and nodes should join that elected master node
