push column projection down to HBase handler's getSplits
--------------------------------------------------------
Key: HIVE-1390
URL: https://issues.apache.org/jira/browse/HIVE-1390
Project: Hadoop Hive
Issue Type: Improvement
Components: HBase Handler
Affects Versions: 0.6.0
Reporter: John Sichi
Assignee: John Sichi
Fix For: 0.6.0
We already push down column projections for the actual scans; maybe we should
do the same for getSplits? I don't think it makes a difference currently
(since HBase determines the splits based on the regions), but in the future, if
they get smarter and adjust the splits based on column volumetrics, then this
might make a difference as an optimization.
