Sean Busbey resolved ACCUMULO-2224.
-----------------------------------
Resolution: Fixed
> ZooSession should be more robust to transient DNS issues
> --------------------------------------------------------
>
> Key: ACCUMULO-2224
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2224
> Project: Accumulo
> Issue Type: Bug
> Components: client
> Affects Versions: 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.5.0
> Environment: 1.4.5-SNAP on CDH4 w/gremlins
> Reporter: Sean Busbey
> Assignee: Sean Busbey
> Priority: Minor
> Fix For: 1.4.5, 1.5.1, 1.6.0
>
>
> While injecting network faults, I found that transient DNS problems caused us
> to bail out of ZooSessions rather than retrying as we do for all other IO
> problems. We should retry these failures just as we do for Connection Refused
> or other networking problems.
> Since the addition of ACCUMULO-131, we can be sure that we won't retry actual
> invalid hosts for ever. Instead, after the time out period that holds for all
> other problems we'll properly exit.
> The warn messages logged for IOExceptions should suffice to indicate
> improperly specified host names.
