Xuefu Zhang commented on HIVE-7048:
-----------------------------------
[~swarnim] I'm not sure if I understand your statement of scan filter "would
work but probably won't buy us much in terms of performance". Since the
predicate pushed down is the first segment of the HBase row key, then the
ranged scan would be more efficient than a full table scan. Did I miss anything?

> HIVE-6411 introduced a more generic way to provide composite key
> implementations via custom factory implementations. However it seems like the
> CompositeHBaseKeyFactory implementation uses a FamilyFilter for row key scans
> which doesn't seem appropriate. This should be investigated further and if
> possible replaced with a RowRangeScanFilter.
