Hey [~zsombor.klara]. Please feel free to take a stab if you have time. Unfortunately I am
very occupied for next few weeks but can definitely help answer any questions.

> 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.
