An SGA must still be executed since that's what allows us to change the copyright, along with relicensing (which, as you say, is not needed in this case). -- Brane > As far as the PPMC is Ok with handling the > additional dev. load. > > With my Apache Bigtop hat on, I'd say it'd be even better as we'll be able to > use the Apache Incubator project instead of the current github source. > > Cos > > On Tue, Dec 30, 2014 at 10:56AM, Dmitriy Setrakyan wrote: >> Hi, >> >> I want to open up a discussion about adding GridGain Hadoop Accelerator as >> a feature of Apache Ignite. >> >> As some of you may know, Hadoop Accelerator is now offered as a part of >> GridGain open source edition.
