---------------------------------
Hi Arpit,
I've not seen a pressing need for this yet, given that the messages are
informative enough. So I'm ok if we're not doing this.
Maybe it would be worth it in future, for the code, to have like a single
"deprecation log" channel, toggle-able at the global, package and class levels.
Same could be done for scripts I think.
> add the ability to suppress the deprecated warnings when using hadoop cli
