Navis commented on HIVE-6654: ----------------------------- Views are regarded as sub-queries and current simple fetch optimizer does not accept those, which seemed to be harsh. I'll take look at this later. > SimpleFetchOptimizer ignores views > ---------------------------------- > > Key: HIVE-6654 > URL: https://issues.apache.org/jira/browse/HIVE-6654 > Project: Hive > Issue Type: Bug > Components: Query Processor > Affects Versions: 0.13.0 > Reporter: Gopal V > Attachments: HIVE-6654-test.tgz > > > SimpleFetchOptimizer optimizes "select * from session_orc limit 1;" > But when an alias view is created like "create view session as select * from > session_orc"; > The simple fetch optimizer fails to kick in and optimize away "select * from > session limit 1;" as a fetch only task. -- This message was sent by Atlassian JIRA (v6.2#6252)
