Subject Re: SQL layer over Accumulo?

Thanks for reaching out.

Like Eric said, I'm a little scared because I know that Phoenix is 
rather baked into HBase's API. But, that's half the fun in writing some 
new code :)

I'd be happy to help evaluate what this would look like - what is 
different (both good and bad) in Accumulo. Like was previously 
mentioned, targeting the Accismus (Percolator) prototype to generate the 
secondary indices would, IMO, be the best target here. I know it's in 
the very early stages right now, but I still believe that it would be 
the long-term solution.
