[~jmhsieh] Thanks for bring this up. I am working on HBASE-14849, and also

for it.

> 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.
