INLINE COMMENTS
  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.
