Subject [jira] [Commented] (HIVE-2478) Support dry run option in hive
Date Wed, 04 Jan 2012 02:38:39 GMT


Phabricator commented on HIVE-2478:

khorgath has commented on the revision "HIVE-2478 [jira] Support dry run option in hive".

  ql/src/test/queries/clientnegative/dryrun_bad_fetch_serde.q:1 Hmm.. ok, this is funny -
if I try adding comments (using double hyphen) to the .q script, I get parse failures from
the testcase runner.  And a number of other .q tests don't have comments either, so I don't
see what format I can use to comment.

  How do I add comments here?

  -- comment  : does not work
  # comment : does not work
  // comment : does not work
  /* comment */ : does not work

> 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.
