Subject [jira] [Commented] (HIVE-2478) Support dry run option in hive
Date Tue, 08 Nov 2011 19:21:52 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13146486#comment-13146486
] 

John Sichi commented on HIVE-2478:
----------------------------------

Yes, it does execute user-defined code, e.g. for resolving the types of UDF invocations. 
Without that, you'd have to stop immediately after ANTLR parsing (pure syntax check, no semantic
analysis).

> Hive currently doesn't support a dry run option. For some complex queries we just want
to verify the query syntax initally before running it. A dry run option where just the parsing
is done without actual execution is a good option.
