----------------------------------------

[~zhanzhang] help me out here -- where did the warnings you included come from? 
was that by adding the -feature flag somehow? is that what the compiler warning 
turns into?

I got the ones I quoted from here[1] and compared against the precommit build 
of the patch committed right this one here [2].

Looking at the precommit build for HBASE-14849, the warning quote above is 
still there [3]

> This is a sub-jira of HBASE-14789.  This jira is to focus on the replacement 
> of TableInputFormat for a more custom scan implementation that will make the 
> following use case more effective.
> Use case:
> In the case you have multiple scan ranges on a single table with in a single 
> query.  TableInputFormat will scan the the outer range of the scan start and 
> end range where this implementation can be more pointed.
