Haibo Chen commented on MAPREDUCE-6201:
---------------------------------------
Thanks for the clarification, [~rkanter]. While I agree with you on that if the
disk full we'll hit all other problems first, I am not sure if that is
necessarily the best thing in this particular test. In testNetworkedJob, before
we check cluster status, we submit a job to the cluster. If the job fails
mysteriously because of the disk space issue, that will only make debugging the
test failure even harder. Thus, I think if we cannot make the failure surface
both clearly and early, we should add assert messages to give some hints on the
cause.
