[jira] Created: (HADOOP-4367) Hive: UDAF functions cannot handle
NULL values
Hive: UDAF functions cannot handle NULL values
----------------------------------------------
Key: HADOOP-4367
URL: https://issues.apache.org/jira/browse/HADOOP-4367
Project: Hadoop Core
Issue Type: Bug
Components: contrib/hive
Reporter: Zheng Shao
Assignee: Zheng Shao
The UDAF functions cannot handle null values. It just throws a NullPointerException. We should properly handle null values in UDAF.
For all UDAF functions that we have now: sum, count, ave, we should ignore the null values.
