It's probably the same thing as with Spark. Spark doesn't actually
work with YARN 'beta'-era releases, but works 'stable' and specially
supports 'alpha'. CDH 4.{2-4} or so == YARN 'beta' (not non-standard,
but, is probably the only distro of it you'll still run into in
circulation). (And so it's kind of unhelpful that Spark has build
instructions for CDH 4.2 + YARN.) Yeah, that's the thing you may
handle as a corner case, or not handle and punt to the vendor. But
even that -- if that's the same issue -- it's not a question of
supporting a vendor but a Hadoop version combo.On Mon, Aug 18, 2014 at 5:43 PM, Stephan Ewen <[email protected]> wrote: > I think the main problem was that CDH4 is a non standard build.
