ujc714 opened a new pull request #2616: URL: https://github.com/apache/hive/pull/2616
### What changes were proposed in this pull request? Fix a bug in HiveExpandDistinctAggregatesRule.getGroupingIdValue() which causes "COUNT(DISTINCT COL)" function returns wrong result. ### Why are the changes needed? If there are more than 32 COUNT(DISTINCT COL)" function in a query, the values returned from HiveExpandDistinctAggregatesRule.getGroupingIdValue() overflow so these COUNT functions return 0. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? mvn test -Dtest=TestMiniTezCliDriver -Dqfile=multi_count_distinct.q -- This is an automated message from the Apache Git Service.
