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:
|iteration|ms |s |duration (ms)|duration (s)|

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
Closes#11924
Removed ParseField#match variant that accepts the field name only, without parse flags. Such a method is harmful as it defaults to empty parse flags, meaning that no deprecation exceptions will be thrown in strict mode, which defeats the purpose of using ParseField. Unfortunately such a method was used in a lot of places were the parse flags weren't easily accessible (outside of query parsing), and in a lot of other places just by mistake.
Parse flags have been introduced now as part of SearchContext and mappers where needed. There are a few places (e.g. java api requests) where it is not possible to retrieve them as they depend on the index settings, in that case we explicitly pass in EMPTY_FLAGS for now, but this has to be seen as an exception.
Closes#11859
This commit changes MessageChannelHandler to not skip the underlying
ChannelBuffer while a StreamInput is open on top of it. In case eg. compression
is enabled, this prevents failures due to the fact that the decompressed
stream input expects a certain structure that it can't verify if the position
of the underlying buffer is changed.
Added dynamic arguments to `ElasticsearchException`, `ElasticsearchParseException` and `ElasticsearchTimeoutException`.
This helps keeping the exception messages clean and readable and promotes consistency around wrapping dynamic args with `[` and `]`.
This is just the start, we need to propagate this to all exceptions deriving from `ElasticsearchException`. Also, work started on standardizing on lower case logging & exception messages. We need to be consistent here...
- Uses the same `LoggerMessageFormat` as used by our logging infrastructure.
The work around for resolving `now` doesn't need to be used for aliases, becuase alias filters are parsed at search time. However it can't be removed, because the percolator relies on it.
Parent/child can be specified again in alias filters, this now works again because alias filters are parsed at search time. Parent/child will also use the late query parse work around, to make sure to do the final preparations when the search context is around. This allows the aliases api to validate the parent/child queries without failing because there is no search context.
Closes#10485
Eventually, the field type should not need any names, because there
will be only one name which leads to finding it (the full name, which is
also the index name). However, the short or "simple" name (using java
terminology for class names) is needed just in a couple places, for
serialization.
This change moves the simple name out of MappedFieldType.Names, into
Mapper, and makes Mapper and FieldMapper abstract classes.
Today we loose the RestStatus code for non-serializable exceptions.
This can be tricky if they are supposed to signal certain situations
like authentication errors etc. This commit adds support for carrying on
the exceptions in the NotSerializableExceptoinWrapper
The filters aggregation now has an option to add an 'other' bucket which will, when turned on, contain all documents which do not match any of the defined filters. There is also an option to change the name of the 'other' bucket from the default of '_other_'
Closes#11289
This change means that when the skip gap policy is used, the bucket script aggregation will skip executing the script on a bucket if any of the required bucket_paths are missing for the bucket. No aggregation will be added to the bucket, and the aggregation will move to the next bucket.
This commit changes the postrm script so that it prints error messages instead of failing & exiting when the deletion of a directory failed while removing a RPM/DEB package.
Closes#11373
This allows a lot of null checks to be removed where we were always falling back to the ValueFormat.RAW anyway. Now the format is set to ValueFormat.RAW when no alternative is suitable.
Closes#10594
Field stats index constraints allows to omit all field stats for indices that don't match with the constraint. An index
constraint can exclude indices' field stats based on the `min_value` and `max_value` statistic. This option is only
useful if the `level` option is set to `indices`.
For example index constraints can be useful to find out the min and max value of a particular property of your data in
a time based scenario. The following request only returns field stats for the `answer_count` property for indices
holding questions created in the year 2014:
curl -XPOST 'http://localhost:9200/_field_stats?level=indices' -d '{
"fields" : ["answer_count"] <1>
"index_constraints" : { <2>
"creation_date" : { <3>
"min_value" : { <4>
"gte" : "2014-01-01T00:00:00.000Z",
},
"max_value" : {
"lt" : "2015-01-01T00:00:00.000Z"
}
}
}
}'
Closes#11187
"Root" is a very confusing term for meta field mappers. This change
renames "RootMapper" to "MetadataFieldMapper" and simplifies
how metadata mappers are setup.
It also requires that metadata mappers are now a FieldMapper
(MetadataFieldMapper extends from AbstractFieldMapper). The only
use of a root mapper that wasn't a field mapper was the theoretical
"external" root mapper (just a test mapper). But it doesn't make
sense to not have an actual field, and this falls inline with
the hopefully eventual collapsing of AbstractFieldMapper/FieldMapper/Mapper.
- shard listing actions underpinning shard allocation do not have access to that new node yet (causing errors during shard allocation see #11923
- the very first cluster state published to a node already has shard assignments to it. This surfaced other issues we are working to fix separately
This commit changes the reroute to be done post processing the initial join cluster state to side step these issues while we work on a longer term solution.
Closes#11960
We had several problems with Java Serializatin in the past. At some point
in the Java 1.7.x series JDKs where not compatible anymore when java
serialization (ObjectStream) was used to exchange objects. In elasticsearch
we used this to serialize exceptions across the wire which caused several problems
with incompatible JDKs. While causing lot of trouble this essentially prevented
users from moving forward and upgrade their JVMs. To prevent these kind of issues
this commit removes the dependency on java serialization entirely and bans the
usage of ObjectOutputStream and ObjectInputStream entirely.
Yet, we can't fully serialize all exception anymore such that this commit
is best effort and adds hand written serialization to all elasticsearch exceptions
as well to a selected set of JDK and Lucene exceptions. (see StreamOutput#writeThrowable /
StreamInput.readThrowable). Stacktraces should be preserved for all exceptions while
several names might be replaced with ElasticsearchException if there is no mapping for
the given exception.
In order to support older RPM based distributions like CentOS5,
we should have one RPM available, which is not signed.
This commit creates an unsigned RPM first, then moves it over to
target/releases during the build, then builds a signed RPM.
The unsigned one is uploaded via S3, where as the signed one is
used for the repositories.
In addition, you can now build an RPM without having to specify
any gpg credentials due to offloading this into a maven profile
that is only activated when specifying `rpm.sign` property.
