Edward Capriolo commented on HIVE-3585:
---------------------------------------

+1 with one minor comment. It seems like the SELECT in the q tests are all 'SELECT *' those
do not really test the map/reduce path. Please do a column pruning operation like select col1,
or select distinct(column1).

SerDe,seems fastutil is a good choice.the shark project use fastutil library as columnar serde
