Sushanth Sowmyan commented on HIVE-2478: ---------------------------------------- Hi, I have a question - does EXPLAIN execute any user-specified code? I'm faced with a environment issue where I don't want to execute any user-specified code (UDFs,etc) or run anything, merely to syntax check. Would EXPLAIN still fit my need? Thanks! > Support dry run option in hive > ------------------------------ > > Key: HIVE-2478 > URL: https://issues.apache.org/jira/browse/HIVE-2478 > Project: Hive > Issue Type: Improvement > Components: Configuration > Affects Versions: 0.9.0 > Reporter: kalyan ram > Priority: Minor > Attachments: HIVE-2478-1.patch > > > 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. -- This message is automatically generated by JIRA.
