-----------------------------------------
[~gopalv] do we still need this now that HADOOP-11772 is resolved?
> LLAP: Tez heartbeats are delayed by ~500+ ms due to Hadoop IPC client

> HADOOP-11772 has a clearer bug report of the core issue inside hadoop-common.
> Due to the delayed heartbeats reaching the AM, the reducers are losing up-to
> a couple of seconds for a 60ms (x10 parallel) mapper + 300ms reducer instead
> of finishing the query in under a second.
