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} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
