@InterfaceAudience.Public @InterfaceStability.Stable public abstract ApplicationAttemptId getApplicationAttemptId()
ApplicationAttemptId
of the application to which the
Container
was assigned.
Note: If containers are kept alive across application attempts via
ApplicationSubmissionContext.setKeepContainersAcrossApplicationAttempts(boolean)
the ContainerId
does not necessarily contain the current
running application attempt's ApplicationAttemptId
This
container can be allocated by previously exited application attempt and
managed by the current running attempt thus have the previous application
attempt's ApplicationAttemptId
.
