Hi, Any ideas why Samza can't start a container while running hello-samza on CDH5.4?
It runs fine on local grid. But when running on cluster I can see it talks fine to YARN's ResourceManager and Kafka, get's resources, but fails to start container. At first, I thought it's because CDH5.4 uses YARN 2.6.0, while Samza uses 2.6.1, so I recompiled Samza with YARN 2.6.0 and re-assambled hello-samza. No luck so far. Also, I thought it's because of different protobuf version, but I checked, it's the same in CDH and Samza. Followed http://samza.apache.org/learn/tutorials/0.10/deploy-samza-to-CDH.html to deploy.
