Project: Spark
Issue Type: Bug

org.apache.hadoop.ipc.RemoteException: Server IPC version 7 cannot communicate
with client version 4
When I launch SPARK 1.0.2 on Hadoop 2 in a new EC2 cluster, the above tachyon
exception is thrown when "Formatting JOURNAL_FOLDER".
No exception occurs when I launch on Hadoop 1.
Launch used:
./spark-ec2 -k spark_cluster -i /home/ec2-user/kagi/spark_cluster.ppk
--zone=us-east-1a --hadoop-major-version=2 --spot-price=0.0165 -s 3 launch

*** I don't have this problem when I launch without the
