@InterfaceAudience.Public @InterfaceStability.Stable public class TaskAttemptID extends TaskAttemptID
TaskID, that this TaskAttemptID belongs to.
Second part is the task attempt number. attempt_200707121733_0003_m_000005_0 , which represents the
zeroth task attempt for the fifth map task in the third job
running at the jobtracker started at 200707121733.
Applications should never construct or parse TaskAttemptID strings
, but rather use appropriate constructors or forName(String)
method.
