Hari Sankar Sivarama Subramaniyan commented on HIVE-6959: --------------------------------------------------------- [~ashutoshc] You are right. I am looking at the issues and will upload a new patch soon. Thanks Hari > Remove vectorization related constant expression folding code once Constant > propagation optimizer for Hive is committed > ----------------------------------------------------------------------------------------------------------------------- > > Key: HIVE-6959 > URL: https://issues.apache.org/jira/browse/HIVE-6959 > Project: Hive > Issue Type: Bug > Reporter: Hari Sankar Sivarama Subramaniyan > Assignee: Hari Sankar Sivarama Subramaniyan > Attachments: HIVE-6959.1.patch > > > HIVE-5771 covers Constant propagation optimizer for Hive. Now that HIVE-5771 > is committed, we should remove any vectorization related code which > duplicates this feature. For example, a fn to be cleaned is > VectorizarionContext::foldConstantsForUnaryExprs(). In addition to this > change, constant propagation should kick in when vectorization is enabled. > i.e. we need to lift the HIVE_VECTORIZATION_ENABLED restriction inside > ConstantPropagate::transform(). -- This message was sent by Atlassian JIRA (v6.2#6252)
