| This class encapsulates a MapReduce job and its dependency. It monitors the |
| states of the depending jobs and updates the state of this job. A job starts |
| in the WAITING state. If it does not have any depending jobs, or all of the |
| depending jobs are in SUCCESS state, then the job state will become READY. If |
| any depending jobs fail, the job will fail too. When in READY state, the job |
| can be submitted to Hadoop for execution, with the state changing into |
| RUNNING state. From RUNNING state, the job can get into SUCCESS or FAILED |
| state, depending the status of the job execution. |
