-------------------------------
Summary: Add support for date datatype in the value based
windowing function
Key: HIVE-10911
URL: https://issues.apache.org/jira/browse/HIVE-10911
Project: Hive
Issue Type: Sub-task
Components: PTF-Windowing
Reporter: Aihua Xu
Currently date datatype is not supported in value based windowing function.
For the following query with hiredate to be date type, an exception will be
thrown.
{{select deptno, ename, hiredate, sal, sum(sal) over (partition by deptno order
by hiredate range 90 preceding) from emp;}}
It's valuable to support such type with number of days as the value difference.
