> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: client, mrv2
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Daryn Sharp
>
> If the client fails to connect to the AM or HS, it will go into a tight loop
> retrying the connection. The log rapidly grows with multiple log lines per
> attempt. Based one of the logs, the client was pounding on the AM ~1000/sec.
