Enum Constant Detail

PLANNED

public static final StageState PLANNED

Stage is planned but has not been scheduled yet. A stage will be in the planned state until, the dependencies of the stage have begun producing output.

SCHEDULING

public static final StageState SCHEDULING

Stage tasks are being scheduled on nodes.

RUNNING

public static final StageState RUNNING

Stage is running.

PENDING

public static final StageState PENDING

Stage has finished executing existing tasks but more tasks could be scheduled in the future.

FINISHED

public static final StageState FINISHED

Stage has finished executing and all output has been consumed.

ABORTED

public static final StageState ABORTED

Stage was aborted due to a failure in the query. The failure was not in this stage.

FAILED

public static final StageState FAILED

Stage execution failed.

public static final Set<StageState> TERMINAL_STAGE_STATES

Method Detail

values

public static StageState[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (StageState c : StageState.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static StageState valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

isDone

public boolean isDone()

Is this a terminal state.

isFailure

public boolean isFailure()

Is this a non-success terminal state.
