LiXin Ge commented on MAPREDUCE-6903:
-
No fail or error tests, some test skipped because of the {{Ignore}} label:
seems the judgement standard of {{hadoop-mapreduce-client-jobclient}} needs
update.
Hi [~xgong], any suggestion for the last patch of this easy fix? Many thanks.

just rebase the patch to see if the unit test always fails.

Can't find why the unit test report a failure status, seems because of some

[~xgong] Thanks for your review and kindly advise. I honestly a newbie in
MapReduce when I create the original patch and didn't go a step further to make
the patch better when rebase it these days.
patch 003 have fixed the issue according to your hint, thanks.
BTW, {{TimelineServicePerformance}} can run with {{SimpleEntityWriterV1}} now,
but still have some exception with {{SimpleEntityWriterV2}}, if needed, maybe
another Jira to fix that?
