After upgrading shard might start relocating again. If there are no
replicas the cluster state of a node might not be up to data for
a few miliseconds and direct a search request to a node that does not
have the shard anymore. This result in the following test failures:
1> java.lang.AssertionError: Count is 99 but 101 was expected. Total shards: 13 Successful shards: 12 & 0 shard failures:
1> __randomizedtesting.SeedInfo.seed([1932F73B458703CA:6F4FAD3DAC55591C]:0)
1> [...org.junit.*]
1> org.elasticsearch.test.hamcrest.ElasticsearchAssertions.assertHitCount(ElasticsearchAssertions.java:184)
1> org.elasticsearch.bwcompat.BasicBackwardsCompatibilityTest.testIndexRollingUpgrade(BasicBackwardsCompatibilityTest.java:358)
Waiting for relocation finished should fix this.
Today we have several upgrade methods that can read state written
pre 0.90 or even pre 0.19. Version 2.0 should not support these state
formats. Users of these version should upgrade to a 1.x or 0.90.x version
first.
Closes#8850
This commit removes the deprecated constant for the main
version and uses the real lucene version we are running instead.
Behind the scenes the same value was used and is now obsolet.
Modifications to LoggingListener pushed with #8820 caused the original logger levels not to be reset after modifications, as the new state was saved for restore instead of the previous one.
Added unit tests for LoggingListener as well.

1. Enable the repository using "add-apt-repository" to avoid this error "No command 'deb' found".
2. Adding "sudo" to update and install command.
Closes#8691
Restrict use of java.io.File to 5 methods (excluded), but otherwise ban.
This is a prerequisite to do any mocking here.
I don't try to do any heavy cleanup on these tests, I am not familiar with them.
So this is mostly a rote straightforward conversion.
Closes#8836
This is a start to exposing memory stats improvements from Lucene 5.0.
This adds the following categories of Lucene index pieces to index stats:
* Terms
* Stored fields
* Term Vectors
* Norms
* Doc values
This commit add the engines reference to the store out of the actual
implementation into the hodler since the holder manages the actual lifcycle.
Engine internal references like per searcher or per recovery are kept inside
the actual implemenation since the have a different lifecycle.
Once the current engine is started you can only close it once. Once closed the engine cannot be started again. This commit adds a stop method which signals the engine to free it's resources but in a way that allows restarting.
This is done by introducing InternalEngineHolder which is a wrapper around InternalEngine. This allows to add the stop() method without adding complexity the engine implementation. InternalEngineHolder also serves an entry point for listeners (incoming and outgoing) to other ES components, which removes the needs add/remove them if the engine is stopped.
Closes#8784
Today we try to fetch a shard Id for a given IndexReader / LeafReader
by walking it's tree until the lucene internal SegmentReader and then
casting the directory into a StoreDirecotory. This class is fully internal
to Elasticsearch and should not be exposed outside of the Store.
This commit makes StoreDirectory a private inner class and adds dedicated
ElasticsearchDirectoryReader / ElasticserachLeafReader exposing a ShardId
getter to obtain information about the shard the index / segment belogs to.
These classes can be used to expose other segment specific information in
the future more easily.
When a scoring script returns not a number, the current message is confusing (IllegalArgumentException[docID must be >= 0 and < maxDoc=3 (got docID=2147483647)]). This commit adds the error message ScriptException[script score function returns a wrong score: NaN].
Closes#2426
The packaged init scripts could return an error, if the file
/proc/sys/vm/max_map_count was not existing and we still called
sysctl.
This is primarly to prevent confusing error messages when elasticsearch
is started under virtualized environments without a proc file system.
Closes#4978
Instead of iterating all shards of all indices to get all relocating
shards for a given node we can just use the RoutingNode#shardsWithState
method and fetch all INITIALIZING / RELOCATING shards and check if they
are relocating. This operation is much faster and uses pre-build
data-structures.
Relates to #6372
This commit changes internal callback to be clear
about when they are called and also provide the
exception that was potentially thrown as a callback argument.
Closes#5945
Previously it was possible for the field data clearing in this test to
take too long, causing the test to time out.
This also switches to using `scaledRandomIntBetween` for the number of
fields.
This change will chown /usr/share/elasticsearch/plugins to the elasticsearch
user (the directory was formerly owned by root). This enables the ES user to
manage plugins.
Also, /usr/share/elasticsearch/plugins is now removed when the elasticsearch
package is un-installed. Previously it was left lying there.
Closes#8732

This change adds a systemd service configuration file, and adds systemd logic
to installation and de-installation scripts. The upcoming Debian 8 "Jessie"
release will use systemd.

the recovery diff can return file in the `different` category
since it's conservative if it can't tell if the files are the same.
Yet, the cleanup code only needs to ensure both ends of the recovery
are consistent. If we have a very old segments_N file no checksum is present
but for the delete files they might be such that the segments file passes
the consistency check but the .del file doesn't sicne it's in-fact the same
but this check was missing in the last commit.
