Xiao Chen commented on HADOOP-13669:
------------------------------------
Thanks [~brahmareddy] for the report.... pretty weird I verified in intelliJ
locally on addendum 1 and it passed. Pre-commit also seemed to agree...
But yes now if I run {{mvn compile findbugs:findbugs}} it indeed reports the
issue... Attaching an addendum2 patch to fix, also attaching a trigger patch
since the fix along won't run the relevant pre-commit.
> KMS Server should log exceptions before throwing

> 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.
