---------------------------------------------------------------
Actually my scenario was a little more complex, I have to increase/decrease the
data and BSPTasks for doing experimentation. So, I took your idea and instead
of doing it manually, I wrote a small class which takes all the parameters as
input and divides the files and puts them in HDFS. Path of those files is added
as input to Hama job.

Thank you.

> Exception can occur if the size of splits is bigger than numBSPTasks

> In JonInProgress, it's possble to get Exception in initTasks().
> {code:java}
> this.tasks = new TaskInProgress[numBSPTasks];
> for (int i = 0; i < splits.length; i++) {
> tasks[i] = new TaskInProgress(getJobID(), this.jobFile.toString(),
> splits[i], this.conf, this, i);
> }
> {code}
> I'm not sure that *numBSPTask* is always bigger than *splits.length*.
> So, I think it's better to use bigger value to assign the *tasks* array.
