Josh Elser commented on ACCUMULO-692:
-------------------------------------
??In production, I'd expect usage of nagios or similar monitoring tool.
Displaying the hostname and port in debugging messages helps the novice during
the configuration stage. Also in production, I'd expect the various connections
to be well documented in an operations manual.??
Oops, I misinterpreted your request, my apologies. Read your post to
user@accumulo. I'm not sure I buy hostnames as being so sensitive as to keep
them out of production log files (if someone has access to your logs, they
probably have the ability to netstat and make a pretty good guess about things).
tl;dr Adding hostname:port to exception stacktraces would be good, not sure I
agree with only putting them at DEBUG. The security argument seems excessive to
me. +1 to Corey Nolt's statement about Hadoop/ZooKeeper also placing similar
messages at INFO (follow existing Hadoop conventions).
