INLINE COMMENTS ql/src/java/org/apache/hadoop/hive/ql/Driver.java:479-488 Analysis would be complete but validation won't. I think when some wants a dryrun till analysis they want to know that whether query is semantically valid or not and not just whether semantic analysis phase could be completed successfully. ql/src/java/org/apache/hadoop/hive/ql/Driver.java:944 Didn't get. How come Parse, Analyze get here? I was assuming execution returns if dry mode is set to one of these modes. Also, now that we have agreed to get rid of OFF, this needs to be modified anyways. If you still plan not to use PLAN, then I think that should be removed from enum, since else it sounds confusing to me. ql/src/test/queries/clientnegative/dryrun_bad_fetch_serde.q:1 Try: -- comment Note don't put ; at the end of line.

INLINE COMMENTS ql/src/java/org/apache/hadoop/hive/ql/Driver.java:135-140 PLAN is not explicitly used anywhere in code, because we need to only check 3 times to establish the 4 states. The first two checks happen in the compile part : First check is for PARSE, if it's PARSE, it's weeded out and if not, it continues. Second check is for ANALYZE, if it's that, it's weeded out and if not, it continues. The third check is after the compile, and thus, done for whether it's not-OFF(because both the PARSE and ANALYZE returns return here too, and we weed out all the non-OFF cases there.) I think I agree that an empty string would serve better than OFF, looking to change that. common/src/java/org/apache/hadoop/hive/conf/HiveConf.java:558 Ok, fixing along with trying to make OFF an empty string in the next patch. ql/src/java/org/apache/hadoop/hive/ql/Driver.java:423 Good spot, changing. ql/src/java/org/apache/hadoop/hive/ql/Driver.java:452 Yup. Without this, it does, because it tries to read .getFields() on the schema. Adding comment. ql/src/java/org/apache/hadoop/hive/ql/Driver.java:479-488 Oh, ok - I wasn't entirely sure of that, given the LOG.info proclaiming semantic analysis was complete before the validation. Would the plan validation not count as part of the plan phase? ql/src/java/org/apache/hadoop/hive/ql/Driver.java:944 Disagree. PARSE, ANALYZE and PLAN all come up to here, and need to be rejected. !OFF is the correct check here. ql/src/test/queries/clientnegative/dryrun_bad_fetch_serde.q:1 Ok, doing so.

Issue Type: Improvement
Components: Configuration
Affects Versions: 0.9.0
Reporter: kalyan ram
Priority: Minor
Attachments: HIVE-2478-1.patch, HIVE-2478-2.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.

[ https://issues.apache.org/jira/browse/HIVE-2478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=13120272#comment-13120272 ] John Sichi commented on HIVE-2478: -- Can't you already use EXPLAIN for this purpose? 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.
