Method Details

remoteShardFailed

public void remoteShardFailed(ShardId shardId,
 String allocationId,
 long primaryTerm,
 boolean markAsStale,
 String message,
 @Nullable
 Exception failure,
 ActionListener<Void> 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.

markAsStale - whether or not to mark a failing shard as stale (eg. removing from in-sync set) when failing the shard.

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,
 String message,
 @Nullable
 Exception failure,
 ActionListener<Void> 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,
 String message,
 @Nullable
 Exception failure,
 ActionListener<Void> listener,
 ClusterState currentState)

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

waitForNewMasterAndRetry

protected void waitForNewMasterAndRetry(String actionName,
 ClusterStateObserver observer,
 TransportRequest request,
 ActionListener<Void> listener,
 Predicate<ClusterState> changePredicate)

shardStarted

public void shardStarted(ShardRouting shardRouting,
 long primaryTerm,
 String message,
 ShardLongFieldRange timestampRange,
 ActionListener<Void> listener)

shardStarted

public void shardStarted(ShardRouting shardRouting,
 long primaryTerm,
 String message,
 ShardLongFieldRange timestampRange,
 ActionListener<Void> listener,
 ClusterState currentState)
