Kihwal Lee commented on HDFS-5803:
----------------------------------
I just wanted make sure that the test timeout is not due to regression in the
core code. It looks like the trunk version has 3 extra test cases and
{{testExitZeroOnSuccess}} accounts for most of the extra execution time. I did
not see any sign of performance regression in the three common ones.
+1 for the patch.
