Project: HBase
Issue Type: Improvement

Minor annoyance, when starting a master I very often get 1 or more stack traces
like these:

1) it's not super clear what's going on (putting myself in a new user's head)
and 2) those exceptions look bad (until you see they are at INFO level).
I'd just do a little cleanup: remove the stack trace, add a more meaningful
message.
