Jesus Camacho Rodriguez updated HIVE-13804:
-------------------------------------------
Target Version/s: (was: 2.1.0)
> Propagate constant expressions through insert
> ---------------------------------------------
>
> Key: HIVE-13804
> URL: https://issues.apache.org/jira/browse/HIVE-13804
> Project: Hive
> Issue Type: Sub-task
> Components: CBO
> Affects Versions: 2.1.0
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
>
> Follow-up of HIVE-13068.
> The problem is that CBO optimizes the select query and then the insert part
> of the query is attached; after HIVE-13068, ConstantPropagate in Hive does
> not kick in anymore because CBO optimized the plan, thus we may miss
> opportunity to propagate constant till the top of the plan.
> Ex. ql/src/test/results/clientpositive/cp_sel.q.out
> {noformat}
> insert overwrite table testpartbucket partition(ds,hr) select
> key,value,'hello' as ds, 'world' as hr from srcpart where hr=11;
> {noformat}
