Siying Dong commented on HIVE-2352:
-----------------------------------
I ran tests twice. Both crashed. I think it is an important patch and will
improve latency of some queries (like scanning a large dataset for one or two
rows) dramatically (Currently I sometimes do a "ORDER BY LIMIT BY" to speed it
up if I know the data set is small). We should raise the priority.
