------------------------------

             Summary: UDAF: Add an `approx_distinct` to Hive
                 Key: HIVE-20490
                 URL: https://issues.apache.org/jira/browse/HIVE-20490
             Project: Hive
          Issue Type: Improvement
          Components: UDF
    Affects Versions: 4.0.0
            Reporter: Gopal V


This gives a direct pathway to call the equivalent of Hive's default 
compute_stats() UDAF which computes a HyperLogLog bitVector + approx distinct 
on a column.
