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.

Just like specifying `?preference=_primary`, this adds the ability to
specify `?preference=_replica` or `?preference=_replica_first` on
requests that support it.
Resolves#12222
This action is a liveness test added in #8763 . It should be excluded, just like the fault detection logic or things become overly chatty.
Closes#12291
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.
Closes#10677
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
1. tests don't have a bogus test dependency on zips anymore,
instead we handle this in pre-integration-test. This reduces
lots of confusion for e.g. mvn clean test.
2. refactor integ logic so that core/ and plugin/ share it.
previously they were duplicates but the above change simplifies life.
it also makes it easier for doing more interesting stuff
Require urls for URL repository to be listed in repositories.url.allowed_urls setting. This change ensures that only authorized URLs can be accessed by elasticsearch
