Method Detail

remoteShardFailed

public void remoteShardFailed(ShardId shardId,
                              java.lang.String allocationId,
                              long primaryTerm,
                              java.lang.String message,
                              @Nullable
                              java.lang.Exception failure,
                              ShardStateAction.Listener listener)

Send a shard failed request to the master node to update the cluster state with the failure of a shard on another node. This means that the shard should be failed because a write made it into the primary but was not replicated to this shard copy. If the shard does not exist anymore but still has an entry in the in-sync set, remove its allocation id from the in-sync set.

Parameters:

shardId - shard id of the shard to fail

allocationId - allocation id of the shard to fail

primaryTerm - the primary term associated with the primary shard that is failing the shard. Must be strictly positive.

message - the reason for the failure

failure - the underlying cause of the failure

listener - callback upon completion of the request

localShardFailed

public void localShardFailed(ShardRouting shardRouting,
                             java.lang.String message,

                             java.lang.Exception failure,
                             ShardStateAction.Listener listener)

Send a shard failed request to the master node to update the cluster state when a shard on the local node failed.

localShardFailed

public void localShardFailed(ShardRouting shardRouting,
                             java.lang.String message,
                             @Nullable
                             java.lang.Exception failure,

                             ClusterState currentState)

Send a shard failed request to the master node to update the cluster state when a shard on the local node failed.
