Determines the relevant event(s) that will assist in scheduling downstream vertex connected via a edge with CONCURRENT EdgeProperty.SchedulingType.

Enum Constant Summary

Enum Constants

Enum Constant and Description
SOURCE_TASK_STARTED trigger tasks scheduling for downstream vertex(es) by "running" event(s) of upstream tasks this will be fully supported with TEZ-3999
SOURCE_VERTEX_CONFIGURED trigger tasks scheduling for downstream vertex(es) upon upstream being configured this effectively simultaneously schedules downstream and upstream vertices connected on both ends of a concurrent edge.

Enum Constant Detail

SOURCE_VERTEX_CONFIGURED

public static final EdgeProperty.ConcurrentEdgeTriggerType SOURCE_VERTEX_CONFIGURED

trigger tasks scheduling for downstream vertex(es) upon upstream being configured this effectively simultaneously schedules downstream and upstream vertices connected on both ends of a concurrent edge.

SOURCE_TASK_STARTED

public static final EdgeProperty.ConcurrentEdgeTriggerType SOURCE_TASK_STARTED

trigger tasks scheduling for downstream vertex(es) by "running" event(s) of upstream tasks this will be fully supported with TEZ-3999

Method Detail

values

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

Returns:

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

valueOf

public static EdgeProperty.ConcurrentEdgeTriggerType 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
