Subject [jira] Commented: (HADOOP-1828) [Hbase Shell] Switch Command for sub-shell
Date Mon, 10 Sep 2007 17:42:29 GMT

Izaak Rubin commented on HADOOP-1828:
-------------------------------------

Hi Yoon,

I understand your desire to communicate with the other shell project members, and I agree
that comments like these are a good way of doing so.  However, I think I should clarify that
I myself am not working on the sub-shell implementation; I was only asked to review the patch
and give my feedback.  

The main concern I had with your patch was that it was a bit open-ended and ambiguous.  The
patch itself didn't make the direction or use of the sub-shell clear; it would need additional
patches to make an understandable implementation of sub-shell.  It's just my opinion that
a patch should effect a full, complete change without having to depend on future patches or
issues.
