Hi Patrick What does that means for drop YARN 2.2? seems codes are still there. You mean if build upon 2.2 it will break, and won't and work right? Since the home made akka build on scala 2.10 are not there. While, if for this case, can we just use akka 2.3-M1 which run on protobuf 2.5

Hey Raymond, This won't work because AFAIK akka 2.3-M1 is not binary compatible with akka 2.2.3 (right?). For all of the non-yarn 2.2 versions we need to still use the older protobuf library, so we'd need to support both. I'd also be concerned about having a reference to a non-released version of

Hey Raymond, I just gave what you said a try but have no intentions of maintaining it. You might want it helpful https://github.com/ScrapCodes/incubator-spark/tree/yarn-2.2 incase you are willing to maintain it. For the record, above branch is updated to master with scala 2.10 and uses akka 2.3-M

+1.  Built spark on yarn for both hadoop 0.23 and hadoop 2.2.0 on redhat linux using maven.  Ran some tests on both a secure Hadoop 0.23 cluster and a secure Hadoop 2.2.0 cluster.  Verified signatures and md5. Tom On Tuesday, December 10, 2013 6:49 PM, Patrick Wendell wrote: Please vote

I'd be personally fine with a standard workflow of assemble-deps + packaging just the Spark files as separate packages, if it speeds up everyone's development time. On Wed, Dec 11, 2013 at 1:10 PM, Mark Hamstra wrote: > I don't know how to make sense of the numbers, but here's what I've got > fr

Hi Patrick So what's the plan for support Yarn 2.2 in 0.9? As far as I can see, if you want to support both 2.2 and 2.0 , due to protobuf version incompatible issue. You need two version of akka anyway. Akka 2.3-M1 looks like have a little bit change in API, we probably could i
