> Tez creates JobIDs for tasks by appending the vertex index to the cluster
> timestamp to avoid multiple jobs run in a single Tez session sharing a JobID.
> Hadoop's MagicS3GuardCommitter needs a job-wide UUID to ensure that the task
> committers and the job committer write to/read from the same paths and can
> hence actually commit data. Adding the AM's JobID to the Configuration
> objects allows applications like Hive to pass that as the UUID to the
> committer.
