The context gives the OperatorCoordinator access to contextual information and provides a gateway to interact with other components, such as sending operator events.

  • Method Details

    • getJobID

      org.apache.flink.api.common.JobID getJobID()
      Gets the JobID of the job to which the coordinator belongs.

    • getOperatorId

      OperatorID getOperatorId()
      Gets the ID of the operator to which the coordinator belongs.

    • metricGroup

      org.apache.flink.metrics.groups.OperatorCoordinatorMetricGroup metricGroup()
      Gets the metric group of the operator coordinator.

    • failJob

      void failJob(Throwable cause)
      Fails the job and trigger a global failover operation.

      This operation restores the entire job to the latest complete checkpoint. This is useful to recover from inconsistent situations (the view from the coordinator and its subtasks as diverged), but is expensive and should be used with care.

    • currentParallelism

      int currentParallelism()
      Gets the current parallelism with which this operator is executed.

    • getUserCodeClassloader

      ClassLoader getUserCodeClassloader()
      Gets the classloader that contains the additional dependencies, which are not part of the JVM's classpath.

    • getCoordinatorStore

      CoordinatorStore getCoordinatorStore()
      Gets the CoordinatorStore instance for sharing information between OperatorCoordinators.

    • isConcurrentExecutionAttemptsSupported

      boolean isConcurrentExecutionAttemptsSupported()
      Gets that whether the coordinator supports an execution vertex to have multiple concurrent running execution attempts.

    • getCheckpointCoordinator

      @Nullable CheckpointCoordinator getCheckpointCoordinator()
      Gets the checkpoint coordinator of this job. Return null if checkpoint is disabled.
