Hi
I'd say than no matter what version is running, parameters seem not fit
the cluster that doesn't manage to handle 100 maps that each process a
billion samples : it's hitting the mapreduce timeout of 600 seconds
I'd try with something like 20 100000

Apache Hadoop 0.20 and 0.21 are both very old and unmaintained
releases at this point, and may carry some issues unfixed via further
releases. Please consider using a newer release.
Is there a specific reason you intend to use 0.21.0, which came out of
a branch long since abandoned?
