Chunling Wang commented on HAWQ-1034:
-------------------------------------
The reason why we remove these code is that removing data in table directory in
repair mode will cause risk to lose data. So we decided to not remove data in
table directory in repair mode, which can be replaced by force mode.
> add --repair option for hawq register
