Job Failue, Run it again? Or anything else to do?
I have run my job over night.
But i found that 4 of the maps failed for "java.lang.OutOfMemoryError: Java
heap space" exception.
Do I have to run all the job again? Or anything else I can do with it?

If they failed due to OOM, they'll probably fail again. You might want to
increase the heap-size. And yes if a job has failed, you've to restart the
entire job.
