Akira Ajisaka commented on MAPREDUCE-6682:
------------------------------------------
bq. TestMRCJCFileOutputCommitter: As testCommitter also calling
FileUtil.fullyDelete(new File(outDir.toString())) at the end of testcase,how
about adding in teardown..?
Nice catch!
bq. TestMRTimelineEventHandling: do we need to handle inDir delete also..?
Deleting outDir is sufficient to fix this test failure, but I'm thinking we
should delete inDir as well to avoid possible test failure like this.
I'll update the patch to add {{@After}} method in TestMRCJCFileOutputCommitter.
