Package org.apache.flink.runtime.scheduler.adaptive

Class CreatingExecutionGraph

java.lang.Object
org.apache.flink.runtime.scheduler.adaptive.CreatingExecutionGraph
All Implemented Interfaces:
LabeledGlobalFailureHandler
public class CreatingExecutionGraph extends Object
State which waits for the creation of the ExecutionGraph. If the creation fails, then the state transitions to Finished. If the creation succeeds, then the system tries to assign the required slots. If the set of available slots has changed so that the created ExecutionGraph cannot be executed, the state transitions back into WaitingForResources. If there are enough slots for the ExecutionGraph to run, the state transitions to Executing.

      Specified by:
      handleGlobalFailure in interface LabeledGlobalFailureHandler
      Parameters:
      cause - A cause that describes the global failure.
      failureLabels - Labels providing an additional context about the failure.

    • onLeave

      default void onLeave(Class<? extends org.apache.flink.runtime.scheduler.adaptive.State> newState)
      This method is called whenever one transitions out of this state.
      Parameters:
      newState - newState is the state into which the scheduler transitions

    • as

      default <T> Optional<T> as(Class<? extends T> clazz)
      Tries to cast this state into a type of the given clazz.
      Type Parameters:
      T - target type
      Parameters:
      clazz - clazz describes the target type
      Returns:
      Optional.of(T) target type if the underlying type can be cast into clazz; otherwise Optional.empty()

    • tryRun

      default <T, E extends Exception> void tryRun(Class<? extends T> clazz, org.apache.flink.util.function.ThrowingConsumer<T,E> action, String debugMessage) throws E
      Tries to run the action if this state is of type clazz.
      Type Parameters:
      T - target type
      E - error type
      Parameters:
      clazz - clazz describes the target type
      action - action to run if this state is of the target type
      debugMessage - debugMessage which is printed if this state is not the target type
      Throws:
      E - an exception if the action fails

      action - action to run if this state is of the target type
      invalidStateCallback - that is called if the state isn't matching the expected one.
      Throws:
      E - an exception if the action fails
