Subject [jira] [Commented] (HIVE-11609) Capability to add a filter to hbase scan via composite key doesn't work
Date Wed, 27 Jan 2016 15:37:39 GMT

Yongzhi Chen commented on HIVE-11609:
-------------------------------------

+1 pending on [~swarnim] answering my previous question related to UDFOPEqual (although it
is in the test code, I would like to know why).
For I made some change to the patch, [~szehon] or [~aihuaxu], could you also review the code?
Thanks

> 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.
