Xiao Chen commented on HADOOP-13669:
------------------------------------

Thanks [~jojochuang]! I'll commit end of today then.

+1 on Yetus should improve on this.. I browsed through Yetus code but didn't find an easy
way to fix this. Will create a jira.

> In some recent investigation, it turns out when KMS throws an exception (into tomcat),
it's not logged anywhere and we can only see the exception message from client-side, but not
the stacktrace. Logging the stacktrance would help debugging.
