[jira] [Created] (HIVE-14446) Disable bloom filter for hybrid grace hash join when row count exceeds certain limit

Wei Zheng created HIVE-14446:
--------------------------------

             Summary: Disable bloom filter for hybrid grace hash join when row count exceeds certain limit
                 Key: HIVE-14446
                 URL: https://issues.apache.org/jira/browse/HIVE-14446
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 1.3.0, 2.2.0, 2.1.1
            Reporter: Wei Zheng
            Assignee: Wei Zheng


When row count exceeds certain limit, it doesn't make sense to generate a bloom filter, since its size will be a few hundred MB or even a few GB.
