> During an MR job, ZK expires one of the nodes. This results in losing contact with a
region server and eventually the map task timing out and the job failing.
> Attaching the following logs:
> 1. HBase master logs
> 2. Logs from the web UI
> 3. Logs from the particular RS that went down.
> 4. Logs from the particular node that ZK expired.
