[SPARK-12578][SQL] Distinct should not be silently ignored when used in an
aggregate function with OVER clause
JIRA: https://issues.apache.org/jira/browse/SPARK-12578
Slightly update to Hive parser. We should keep the distinct keyword when
used in an aggregate function with OVER clause. So the CheckAnalysis will
detect it and throw exception later.
