-----------------------------------
Summary: Support multiple partitionings in a single Query
Key: HIVE-4041
URL: https://issues.apache.org/jira/browse/HIVE-4041
Project: Hive
Issue Type: Bug
Components: PTF-Windowing
Reporter: Harish Butani
Assignee: Harish Butani
Currently we disallow queries if the partition specifications of all Wdw fns
are not the same. We can relax this by generating multiple PTFOps based on the
unique partitionings in a Query. For partitionings that only differ in sort, we
can introduce a sort step in between PTFOps, which can happen in the same
Reduce task.
