Hello all, I am running hadoop 2.6.4 with Spark 2.0 and I have been trying to get dynamic allocation to work without success. I was able to get it to work with Spark 16.1 however. When I issue the commandspark-shell --master yarn --deploy-mode client this is the error I see: 16/08/24 00:05:40 WARN NettyRpcEndpointRef: Error sending message [message = RequestExecutors(1,0,Map())] in 1 attemptsorg.apache.spark.rpc.RpcTimeoutException: Futures timed out after [120 seconds].

Container exited with a non-zero exit code 1 If I turn off dynamic allocation, the command works just fine. Are there additional steps beyond what's described in the spark documentation I need to take? Your help is much appreciated, Shane
