Enum VertexTerminationCause

java.lang.Object

java.lang.Enum<VertexTerminationCause>

org.apache.tez.dag.app.dag.VertexTerminationCause

All Implemented Interfaces:

Serializable, Comparable<VertexTerminationCause>

public enum VertexTerminationCause
extends Enum<VertexTerminationCause>

Represents proximate cause of transition to FAILED or KILLED.

Enum Constant Summary

Enum Constants

Enum Constant and Description
AM_USERCODE_FAILURE This vertex failed as its AM usercode (VertexManager/EdgeManager/InputInitializer) throw Exception
COMMIT_FAILURE This vertex failed during commit.
COUNTER_LIMITS_EXCEEDED This vertex failed due to counter limits exceeded.
DAG_TERMINATED DAG was killed
INIT_FAILURE This vertex failed during init.
INTERNAL_ERROR
INVALID_NUM_OF_TASKS This vertex failed as it had invalid number tasks.
OTHER_VERTEX_FAILURE Other vertex failed causing DAG to fail thus killing this vertex
OWN_TASK_FAILURE One of the tasks for this vertex failed.
RECOVERY_ERROR error when writing recovery log
ROOT_INPUT_INIT_FAILURE Initialization failed for one of the root Inputs
VERTEX_RERUN_AFTER_COMMIT In some cases, vertex could not rerun, e.g.
VERTEX_RERUN_IN_COMMITTING Rerun vertex while it is in committing, it would cause conflict.

Method Detail

values

public static VertexTerminationCause[] 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 (VertexTerminationCause c : VertexTerminationCause.values())
    System.out.println(c);

Returns:

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

valueOf

public static VertexTerminationCause 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

getFinishedState

public VertexState getFinishedState()
