public class TransportPrevalidateShardPathAction
extends TransportNodesAction<PrevalidateShardPathRequest,PrevalidateShardPathResponse,NodePrevalidateShardPathRequest,NodePrevalidateShardPathResponse>

Given a set of shard IDs, checks which of those shards have a matching directory in the local data path. This is used by PrevalidateNodeRemovalAction to find out whether a node may contain some copy of a specific shard. The response contains a subset of the request shard IDs which are in the cluster state of this node and have a matching shard path on the local data path.

Method Details

newResponse

protected PrevalidateShardPathResponse newResponse(PrevalidateShardPathRequest request,
 List<NodePrevalidateShardPathResponse> nodeResponses,
 List<FailedNodeException> failures)

Description copied from class: TransportNodesAction

Create a new TransportNodesAction. This method is executed on TransportNodesAction.finalExecutor.

Specified by:

newResponse in class TransportNodesAction<PrevalidateShardPathRequest,PrevalidateShardPathResponse,NodePrevalidateShardPathRequest,NodePrevalidateShardPathResponse>

Parameters:

request - The request whose response we are constructing. TransportNodesAction may have already released all its references to this object before calling this method, so it's up to individual implementations to retain their own reference to the request if still needed here.

nodeResponses - All successful node-level responses.

failures - All node-level failures.

Returns:

Never null.

newNodeRequest

protected NodePrevalidateShardPathRequest newNodeRequest(PrevalidateShardPathRequest request)

Specified by:

newNodeResponse

protected NodePrevalidateShardPathResponse newNodeResponse(StreamInput in,
 DiscoveryNode node)
                                                    throws IOException

Specified by:

newNodeResponse in class TransportNodesAction<PrevalidateShardPathRequest,PrevalidateShardPathResponse,NodePrevalidateShardPathRequest,NodePrevalidateShardPathResponse>

Throws:

IOException

nodeOperation

protected NodePrevalidateShardPathResponse nodeOperation(NodePrevalidateShardPathRequest request,
 Task task)
