Eric Newton commented on ACCUMULO-2224:

What are you using to inject these network faults?

>                 URL:
>             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.
