java.lang.Object

java.lang.Enum<DAGTerminationCause>

org.apache.tez.dag.app.dag.DAGTerminationCause

All Implemented Interfaces:

Serializable, Comparable<DAGTerminationCause>

public enum DAGTerminationCause
extends Enum<DAGTerminationCause>

Represents proximate cause of a DAG transition to FAILED or KILLED.

Enum Constant Summary

Enum Constants

Enum Constant and Description
COMMIT_FAILURE DAG failed during output commit.
DAG_KILL DAG was directly killed.
INIT_FAILURE DAG failed during init.
INTERNAL_ERROR
RECOVERY_FAILURE DAG failed while trying to write recovery events
VERTEX_FAILURE A vertex failed.
VERTEX_RERUN_AFTER_COMMIT In some cases, vertex could not rerun, e.g.
ZERO_VERTICES DAG failed due as it had zero vertices.

public static final DAGTerminationCause DAG_KILL

DAG was directly killed.

VERTEX_FAILURE

public static final DAGTerminationCause VERTEX_FAILURE

A vertex failed.

ZERO_VERTICES

public static final DAGTerminationCause ZERO_VERTICES

DAG failed due as it had zero vertices.

INIT_FAILURE

public static final DAGTerminationCause INIT_FAILURE

DAG failed during init.

COMMIT_FAILURE

public static final DAGTerminationCause COMMIT_FAILURE

DAG failed during output commit.

VERTEX_RERUN_AFTER_COMMIT

public static final DAGTerminationCause VERTEX_RERUN_AFTER_COMMIT

In some cases, vertex could not rerun, e.g. its output been committed as a shared output of vertex group

Method Detail

values

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

Returns:

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

valueOf

public static DAGTerminationCause 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
