Method Details

shards

protected ShardsIterator shards(ClusterState clusterState,
 IndicesSegmentsRequest request,
 String[] concreteIndices)

Segments goes across *all* active shards.

Specified by:

shards in class TransportBroadcastByNodeAction<IndicesSegmentsRequest,IndicesSegmentResponse,ShardSegments>

Parameters:

clusterState - the cluster state

request - the underlying request

concreteIndices - the concrete indices on which to execute the operation

Returns:

the shards on which to execute the operation

checkGlobalBlock

protected ClusterBlockException checkGlobalBlock(ClusterState state,
 IndicesSegmentsRequest request)

Description copied from class: TransportBroadcastByNodeAction

Executes a global block check before polling the cluster state.

Specified by:

checkGlobalBlock in class TransportBroadcastByNodeAction<IndicesSegmentsRequest,IndicesSegmentResponse,ShardSegments>

Parameters:

state - the cluster state

request - the underlying request

Returns:

a non-null exception if the operation is blocked

checkRequestBlock

protected ClusterBlockException checkRequestBlock(ClusterState state,
 IndicesSegmentsRequest countRequest,
 String[] concreteIndices)

Description copied from class: TransportBroadcastByNodeAction

Executes a global request-level check before polling the cluster state.

Specified by:

checkRequestBlock in class TransportBroadcastByNodeAction<IndicesSegmentsRequest,IndicesSegmentResponse,ShardSegments>

Parameters:

state - the cluster state

countRequest - the underlying request

concreteIndices - the concrete indices on which to execute the operation

Returns:

a non-null exception if the operation if blocked

readShardResult

protected ShardSegments readShardResult(StreamInput in)
                                 throws IOException

Description copied from class: TransportBroadcastByNodeAction

Deserialize a shard-level result from an input stream

Specified by:

readShardResult in class TransportBroadcastByNodeAction<IndicesSegmentsRequest,IndicesSegmentResponse,ShardSegments>

Parameters:

in - input stream

Returns:

a deserialized shard-level result

Throws:

IOException

newResponse

protected IndicesSegmentResponse newResponse(IndicesSegmentsRequest request,
 int totalShards,
 int successfulShards,
 int failedShards,
 List<ShardSegments> results,
 List<DefaultShardOperationFailedException> shardFailures,
 ClusterState clusterState)

Description copied from class: TransportBroadcastByNodeAction

Creates a new response to the underlying request.

Specified by:

newResponse in class TransportBroadcastByNodeAction<IndicesSegmentsRequest,IndicesSegmentResponse,ShardSegments>

Parameters:

request - the underlying request

totalShards - the total number of shards considered for execution of the operation

successfulShards - the total number of shards for which execution of the operation was successful

failedShards - the total number of shards for which execution of the operation failed

results - the per-node aggregated shard-level results

shardFailures - the exceptions corresponding to shard operation failures

clusterState - the cluster state

Returns:

the response

readRequestFrom

protected IndicesSegmentsRequest readRequestFrom(StreamInput in)
                                          throws IOException

Description copied from class: TransportBroadcastByNodeAction

Deserialize a request from an input stream

Specified by:

readRequestFrom in class TransportBroadcastByNodeAction<IndicesSegmentsRequest,IndicesSegmentResponse,ShardSegments>

Parameters:

in - input stream

Returns:

a de-serialized request

Throws:

IOException

shardOperation

protected void shardOperation(IndicesSegmentsRequest request,
 ShardRouting shardRouting,
 Task task,
 ActionListener<ShardSegments> listener)

Description copied from class: TransportBroadcastByNodeAction

Executes the shard-level operation. This method is called once per shard serially on the receiving node. This method should not throw an exception, but pass the exception to the listener instead.

Specified by:

shardOperation in class TransportBroadcastByNodeAction<IndicesSegmentsRequest,IndicesSegmentResponse,ShardSegments>

Parameters:

request - the node-level request

shardRouting - the shard on which to execute the operation

task - the task for this node-level request

listener - the listener to notify with the result of the shard-level operation
