Suraj Acharya commented on HADOOP-13669:
----------------------------------------

I agree with the logic of it being a bit too much.
However, my thought process was that since most of these errors will be a fatal error (either killing the operation in progress / killing the startup of the KMS) i thought it was worth putting this as an error message.
But ill take whatever recommendation you'll give me on this one.

> 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.
