Examples of org.apache.hadoop.mapreduce.JobID

org.apache.hadoop.mapreduce.JobID
JobID represents the immutable and unique identifier for the job. JobID consists of two parts. First part represents the jobtracker identifier, so that jobID to jobtracker map is defined. For cluster setup this string is the jobtracker start time, for local setting, it is "local" and a random number. Second part of the JobID is the job number.
An example JobID is : job_200707121733_0003 , which represents the third job running at the jobtracker started at 200707121733.
Applications should never construct or parse JobID strings, but rather use appropriate constructors or {@link #forName(String)} method. @see TaskID @see TaskAttemptID
