Compatibility testing has gone well for me. - In a 4-node cluster, I ran YARN rolling upgrade tests between 2.8.5 and 2.10.0 - In a 4-node cluster, I ran YARN rolling upgrade tests between 2.10.0 and trunk - With one 4-node cluster running 2.10.0 and one 4-node cluster running trunk, I ran a word count job in each cluster whose inputs and outputs were from and to the opposite cluster. - I verified that HDFS replication works as expected in a trunk cluster that has one 2.10.0 datanode.
