> Description:
> * Submit a job to the job tracker and let the job complete its execution through one of the job client's submitJob APIs.
> * Jobclient returns a handle to the job, in the form of a RunningJob object. Client can use this object to check whether job is sucessful or whether job is completed.
> * Reduce the following property *mapred.jobtracker.retirejob.interval*.By default this value is 1 day. I reduced it to 5 min.
> * Set the property *mapred.job.tracker.persist.jobstatus.active* to {color:blue}*false*{color}.
> * Call either isComplete or isSuccessful APIs, after *mapred.jobtracker.retirejob.interval* time period, previously mentioned APIs throw NPE.
