Interface JobTable.Job

Enclosing interface:
JobTable
public static interface JobTable.Job
A job contains services which are bound to the lifetime of a Flink job. Moreover, it can be connected to a leading JobManager and then store further services which are bound to the lifetime of the JobManager connection.

Accessing any methods after a job has been closed will throw an IllegalStateException.

      resourceId - resourceId of the JobManager to connect to
      jobMasterGateway - jobMasterGateway of the JobManager to connect to
      taskManagerActions - taskManagerActions associated with this connection
      checkpointResponder - checkpointResponder associated with this connection
      aggregateManager - aggregateManager associated with this connection
      partitionStateChecker - partitionStateChecker associated with this connection
      Returns:
      the established JobTable.Connection
