> If task profiling is enabled, the JobClient will download the {{profile.out}} file created
by the tasks under profile. If this causes an IOException, the job is reported as a failure
to the client, even though all the tasks themselves may complete successfully. The expected
result files are assumed to be generated by hprof. Using the profiling system with other profilers
will cause job failure.
