All Implemented Interfaces:

Serializable

@InterfaceAudience.Private
public class NoCurrentDAGException
extends TezException

Fatal exception: thrown by the AM if there is no DAG running when a DAG's status is queried. This is different from DAGNotRunningException in a sense that this exception is fatal, in which scenario the client might consider the DAG failed, because it tries to ask a status from an AM which is not currently running a DAG. This scenario is possible in case an AM is restarted and the DagClient fails to realize it's asking the status of a possibly lost DAG.
