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. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
