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.

SCHEDULING_SPLITS

public static final StageState SCHEDULING_SPLITS

All stage tasks have been scheduled, but splits are still being scheduled.

SCHEDULED

public static final StageState SCHEDULED

Stage has been scheduled on nodes and ready to execute, but all tasks are still queued.

RUNNING

public static final StageState RUNNING

Stage is running.

FLUSHING

public static final StageState FLUSHING

Stage has finished executing and output being consumed. In this state, at-least one of the tasks is flushing and the non-flushing tasks are finished

FINISHED

public static final StageState FINISHED

Stage has finished executing and all output has been consumed.

CANCELED

public static final StageState CANCELED

Stage was canceled by a user.

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.

TERMINAL_STAGE_STATES

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.

canScheduleMoreTasks

public boolean canScheduleMoreTasks()
