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.
