Jinho Kim updated TAJO-1025:
----------------------------
Attachment: TAJO-1025.20140922-2.patch
Thank you for your contribution! I'm sorry for confusing.
In my opinion, we should catch two block. because other cases can’t handle
exception. How do you think about the patch (TAJO-1025.20140922-2.patch) ?
In addition, it will be easier for reviewers to leave comments if you upload
your patch to reviewboard (https://reviews.apache.org/dashboard/) or github
pull request (https://github.com/apache/tajo/pulls).
Thanks!
