-----------------------------------------
[~ychena] Thanks for taking a look. Unfortunately I am not 100% sure at this
point why but looking at the sequence of patches it looks like that was in to
address a test failure that was caused by the first patch.

> It seems like the capability to add filter to an hbase scan which was added
> as part of HIVE-6411 doesn't work. This is primarily because in the
> HiveHBaseInputFormat, the filter is added in the getsplits instead of
> getrecordreader. This works fine for start and stop keys but not for filter
> because a filter is respected only when an actual scan is performed. This is
> also related to the initial refactoring that was done as part of HIVE-3420.
