Hi, St.Ack, I agree about both focus and crazy-making grids, and that's why I tried to use "tested with" rather than "supports" (though I see i used "support" for the Linux distributions, oops). Things are moving so quickly here, and the combinations get crazy. If folks select versions that are found on a couple of the common vendor distributions that we'd like to support and test with that, then doing basic sanity checking with the actual vendor distribution should allow us to say that we've tested.
Again, the goal is to make it easy for more people to try Trafodion. I believe that many (most?) of the folks trying Trafodion for their own use cases will come from a distro background, while Trafodion developers are more likely to work with Apache Hadoop as a starting point. To me, that suggests we need to at least think about both. That's why I liked the HBase chart that separated out Supported (or "believe it should work but didn't try it") from Tested. For me, that seemed to be a simple way to tell whether a combination I wanted to try had been tested and was likely to work. Then I could map that to vendor distro. -Carol P. --------------------------------------------------------------- Email: [email protected] Twitter: @CarolP222 --------------------------------------------------------------- On Fri, Feb 5, 2016 at 9:24 AM, Stack <[email protected]> wrote: > On Thu, Feb 4, 2016 at 11:25 PM, Atanu Mishra <[email protected]> > wrote: > >> Hi Carol, >> >> Great question!
