org.apache.hadoop.mapreduce.v2.api.records.JobId

JobId represents the globally unique identifier for a MapReduce job.

The globally unique nature of the identifier is achieved by using the cluster timestamp from the associated ApplicationId. i.e. start-time of the ResourceManager along with a monotonically increasing counter for the jobId.
