Description

We had an issue where the DRPC server (on an older version of storm) was misconfigured and constantly restarting without logging shutdown messages.  One of the warning messages that did log should have been an error and could provide more useful information about fixing the issue.

warning message: 

2018-07-20 15:09:30.191 clojure-agent-send-off-pool-0 b.s.s.a.k.ServerCallbackHandler [WARN] No password found for user: null

 

hopefully more helpful:

2018-07-20 15:44:39.835 clojure-agent-send-off-pool-0 b.s.s.a.k.ServerCallbackHandler [ERROR] No password found for user: null, validate klist matches jaas conf
