Arpit Agarwal resolved HDDS-782.
--------------------------------
Resolution: Abandoned
Let's abandon this one, we have had a huge number of performance improvements
in the last 4-5 years, and this is likely obsolete. We can reopen if we still
suspect a different perf issue.

> On running a hadoop examples pi job it takes 250+ seconds which generally run
> in few seconds in HDFS cluster.
> On seeing the service/job logs it seems that there are few
