Ashutosh Chauhan commented on HIVE-4959: ---------------------------------------- You are walking the plan tree yourself in the optimizer. Hive already has infra for plan walking. I am wondering why not reuse that? That will simplify optimizer code. > Vectorized plan generation should be added as an optimization transform. > ------------------------------------------------------------------------ > > Key: HIVE-4959 > URL: https://issues.apache.org/jira/browse/HIVE-4959 > Project: Hive > Issue Type: Sub-task > Reporter: Jitendra Nath Pandey > Assignee: Jitendra Nath Pandey > Attachments: HIVE-4959.1.patch, HIVE-4959.2.patch > > > Currently the query plan is vectorized at the query run time in the map task. > It will be much cleaner to add vectorization as an optimization step. -- This message is automatically generated by JIRA.
