----------------------------------
Hi David,
While I'm testing this patch, I found some bug (TAJO-705) which already exist
in CTAS operation. I'm suspecting that this bug is recently introduced.
TAJO-705 is blocking some cluster tests. After we fix TAJO-705 as soon as
possible, I'll finish the review of your work.
Thanks,
Hyunsik
