Na Yang commented on HIVE-8561: ------------------------------- [~brocknoland], thank you very much for the suggestion. I will change the annotation to be Unstable after getting [~jpullokkaran] 's input. [~jpullokkaran], I appreciate if you could give some suggestions on how to let Drill and other projects to be able to use the Hive query plan. Thanks. > Expose Hive optiq operator tree to be able to support other sql on hadoop > query engines > --------------------------------------------------------------------------------------- > > Key: HIVE-8561 > URL: https://issues.apache.org/jira/browse/HIVE-8561 > Project: Hive > Issue Type: Task > Components: CBO > Affects Versions: 0.14.0 > Reporter: Na Yang > Assignee: Na Yang > Attachments: HIVE-8561.2.patch, HIVE-8561.3.patch, HIVE-8561.patch > > > Hive-0.14 added cost based optimization and optiq operator tree is created > for select queries. However, the optiq operator tree is not visible from > outside and hard to be used by other Sql on Hadoop query engine such as > apache Drill. To be able to allow drill to access the hive optiq operator > tree, we need to add a public api to return the hive optiq operator tree. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
