Review request for hive.
Bugs: HIVE-7635
https://issues.apache.org/jira/browse/HIVE-7635
Repository: hive-git
Description
-------
A query having same aggregate functions but in different case (e.g. SELECT key,
COUNT(value) FROM src GROUP BY key HAVING count(value) >= 4) does not work and
throws IndexOutOfBoundsException. The cause is that Hive treats count(value)
and COUNT(value) in this query as two different aggregate expression when
compiling query and generating plan. They are case sensitive.
Diffs

-------
1. The fix addressed the failed query with different case in aggregate function
name in the query
2. New unit tests passed
3. patch will be submitted for pre-commit tests
Thanks,
