Subject [jira] [Updated] (HIVE-4812) Logical explain plan
Date Sun, 07 Jul 2013 22:09:49 GMT

     [ https://issues.apache.org/jira/browse/HIVE-4812?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gunther Hagleitner updated HIVE-4812:
-------------------------------------

    Description: 
In various situations it would have been useful to me to glance at the operator plan before
we break it into tasks and apply join, total order sort, etc optimizations.

I've added this as an options to explain. "Explain logical <QUERY>" will output the
full operator tree (not the stage plans, tasks, AST etc).

Again, I don't think this has to even be documented for users, but might be useful to developers.
