Subject [jira] [Resolved] (TAJO-524) zero result
Date Wed, 22 Jan 2014 02:17:20 GMT

]

Hyunsik Choi resolved TAJO-524.
-------------------------------

    Resolution: Fixed

If so, I close this issue.
This may be indirectly caused by other problem like OOM that we dealt with TAJO-522 and TAJO-537.


However, we can know that Query and Subquery does not handle these situations and does not
show exact cause in the case where OOM is caused. According to the command line, it just printed
QUERY_SUCCEEDED.

So, I'll create another jira issue for handling exceptions those cases.
