(Updated Dec. 3, 2014, 7:40 p.m.) Review request for hive and John Pullokkaran. Repository: hive-git Description ------- Right now, even when groupby index is build, CBO is not able to use it. In this patch, we are trying to make it use groupby index that we build. The basic problem is that for SEL1-SEL2-GRY-...-SEL3, the previous version only modify SEL2, which immediately precedes GRY. Now, with CBO, we have lots of SELs, e.g., SEL1. So, the solution is to modify all of them.
