Swarnim Kulkarni commented on HIVE-11609:
-----------------------------------------
It would current read the scan object from the jobConf and my understanding was
that with the way Kryo works with Hive, lot of this ser and deser happens via
this jobConf and is controlled here[1]. So in order for that object to get into
jobConf, the field had to be "de-transitionized".

> 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.
