Xiaoyu Yao commented on HADOOP-15686:
-------------------------------------
Thanks [~weichiu] for the update. The latest patch LGTM, I verified TestKMS
does not output bogus log messages after the latest patch.
Can you add some verification in TestKMS to capture the LOG output and make
sure it does not contain bogus log message in the description. This way, if
someone break it accidentally in future, we will be able to catch it as part of
the regression test.
