Subject Re: [jira] [Commented] (HORN-2) Umbrella ticket for Implementation Planning of Apache Horn
Date Thu, 24 Sep 2015 14:41:30 GMT
Hi,

I was interested in contributing to Horn, and if there are any papers, or
specific code that I should look at to get up to speed while your on
vacation, feel free to let me know, from the looks of it on JIRA not too
much detailed planning has occurred yet, so there probably isn't specific
tasks or stories that are ready to be worked on yet out side of the
microsite, but if there is, I would also be interested in taking a crack at
that.

Best,
Zach
