Subject [jira] [Commented] (HIVE-3926) PPD on virtual column of partitioned table is not working
Date Tue, 23 Jul 2013 23:10:49 GMT


Phabricator commented on HIVE-3926:

hagleitn has commented on the revision "HIVE-3926 [jira] PPD on virtual column of partitioned
table is not working".

  Some minor comments + request for more info.

  ql/src/java/org/apache/hadoop/hive/ql/ tableScanOperator was actually a clearer
name, wasn't it?
  ql/src/java/org/apache/hadoop/hive/ql/exec/ I think this is redundant.
o instanceof MapInputPath is false if o == null
  ql/src/java/org/apache/hadoop/hive/ql/optimizer/ppr/ can you please
add a javadoc comment here?
  ql/src/java/org/apache/hadoop/hive/ql/exec/ There are a lot of changes
in MapOperator. I've scan through them and it seems most (all?) are just cleaning up the operator
(which is great).

  Is that correct? If not can you please point out what the important changes are?
