> In testing RM and AM failure scenarios, I killed my RM, killed the AM, waited
> for a bit, then restarted the RM. The AM is restarted, but running agents
> never connect to the new AM. The AM data is re-read from the ZK registry once
> if the heartbeat retry threshold is reached, at which point the agent tries
> re-registering with the AM. However, if the AM data is stale at that point,
> it never re-reads the data from the ZK registry, and retries registering with
> the nonexistent AM forever (until it is timed out due to heartbeat loss and
> killed by the new AM).
> Note this happens when AM restart is delayed more than about a minute, which
> can occur if the RM is down or the RM is up but busy.
