Subject Re: [PROPOSAL] Ivory - Hadoop data management and processing platform
Date Wed, 13 Mar 2013 19:48:02 GMT
Hi Srikanth,
I've read the proposal and documentation available on Github and the project seems very interesting
to me. I'm currently mainly focusing on Apache Sqoop [1] and I can see a lot of opportunities
for integration. I'll be more than happy to help with Ivory going forward. In case that you're
open to the idea of "open enrolment", I'll be more than happy to sign up as initial contributor.

P.S. - I found few nits in the docs so I've created github pull request to fix them.
