> In {{AssignmentManager}}'s {{CreateUnassignedAsyncCallback}}, we have the following condition:
> {code}
> if (rc != 0) {
>         // Thisis resultcode.  If non-zero, need to resubmit.
>         LOG.warn("rc != 0 for " + path + " -- retryable connectionloss -- " +
>           "FIX see http://wiki.apache.org/hadoop/ZooKeeper/FAQ#A2");
>         this.zkw.abort("Connectionloss writing unassigned at " + path +
>           ", rc=" + rc, null);
>         return;
> }
> {code}
> While a similar structure inside {{ExistsUnassignedAsyncCallback}} (which the above is
linked to), does not have such a force abort.
> Do we really require the abort statement here, or can we make do without?
