Subject [jira] [Created] (HIVE-9833) udaf_percentile_approx_23.q fails intermittently
Date Tue, 03 Mar 2015 00:52:04 GMT
Wei Zheng created HIVE-9833:

             Summary: udaf_percentile_approx_23.q fails intermittently
                 Key: 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.
