[jira] [Created] (HIVE-9833) udaf_percentile_approx_23.q fails intermittently

Wei Zheng created HIVE-9833:
-------------------------------

             Summary: udaf_percentile_approx_23.q fails intermittently
                 Key: HIVE-9833
                 URL: https://issues.apache.org/jira/browse/HIVE-9833
             Project: Hive
          Issue Type: Bug
          Components: UDF
            Reporter: Wei Zheng


For the query below:

select percentile_approx(case when key < 100 then cast('NaN' as double) else key end, 0.5) from bucket

the base test result is 341.5.

But sometimes it returns 342 during QA testing.

It happens randomly.
