--------------------------------------

bq. All other failures are jdk 1.7 related issues

Yeah, no worries. I have it on my list to try to make this better in the future.

bq. I'm not sure how to write unit tests for this.

Ok. I'll take a look at what you have today and see if I can come up with anything :)

> Accumulo stores hostnames in zookeeper, if the client can not resolve these then it will continue to try to connect in a while(true) loop. This will eventually cause 'too many files open' errors.
> Loop is in ServerClient.java$executeRaw
> Bug: Should error out after some time, not retry infintely.
> Workaround: Add hostnames to /etc/hosts and restart.
