Jesus Camacho Rodriguez resolved HIVE-11049.
--------------------------------------------
Resolution: Duplicate
Closing as duplicate of HIVE-11752. Full integration with CBO is still a
pending task; but support for _spool_ operators needs to be added to Calcite
first.
> With Clause should cache data & reuse

> Key: HIVE-11049
> URL: https://issues.apache.org/jira/browse/HIVE-11049
> Project: Hive
> Issue Type: Improvement
> Reporter: Laljo John Pullokkaran
> Assignee: Jesus Camacho Rodriguez
> Fix For: 1.3.0
>
>
> Hive supports with clause. However Hive don't cache the result set of with
> clause and reuse it.
> Instead we inline the query definition of the with clause. This results in re
> execution of with clause query every where it is referenced.
