Enum Constant Summary

Enum Constants

Enum Constant	Description
EXISTS_BUT_NO_CREATION	2: Means Google Clusters did not find a record representing the creation of the given task or job.
NO_SNAPSHOT_OR_TRANSITION	1: Means Google Clusters did not find a record representing the given termination event, but the job or task disappeared from later snapshots of cluster states, so it must have been terminated.
SNAPSHOT_BUT_NO_TRANSITION	0: Means Google Clusters did not find a record representing the given event, but a later snapshot of the job or task state indicated that the transition must have occurred.

Method Summary

Modifier and Type	Method	Description
static GoogleTaskEventsTraceReader.MissingInfo	valueOf(String name)	Returns the enum constant of this type with the specified name.
static GoogleTaskEventsTraceReader.MissingInfo[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Details

SNAPSHOT_BUT_NO_TRANSITION

public static final GoogleTaskEventsTraceReader.MissingInfo SNAPSHOT_BUT_NO_TRANSITION

0: Means Google Clusters did not find a record representing the given event, but a later snapshot of the job or task state indicated that the transition must have occurred. The timestamp of the synthesized event is the timestamp of the snapshot.

NO_SNAPSHOT_OR_TRANSITION

public static final GoogleTaskEventsTraceReader.MissingInfo NO_SNAPSHOT_OR_TRANSITION

1: Means Google Clusters did not find a record representing the given termination event, but the job or task disappeared from later snapshots of cluster states, so it must have been terminated. The timestamp of the synthesized event is a pessimistic upper bound on its actual termination time assuming it could have legitimately been missing from one snapshot.

EXISTS_BUT_NO_CREATION

public static final GoogleTaskEventsTraceReader.MissingInfo EXISTS_BUT_NO_CREATION

2: Means Google Clusters did not find a record representing the creation of the given task or job. In this case, we may be missing metadata (job name, resource requests, etc.) about the job or task and we may have placed SCHEDULE or SUBMIT events latter than they actually are.

Method Details

values

public static GoogleTaskEventsTraceReader.MissingInfo[] values()

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

Returns:

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

valueOf

public static GoogleTaskEventsTraceReader.MissingInfo 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
