Caused by: org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /checkpoint/11ea8862-122c-4614-bc7e-f761bb57ba23/rdd-347/.part-00001-attempt-3 could only be replicated to 0 nodes instead of minReplication (=1). There are 0 datanode(s) running and no node(s) are excluded in this operation.
This is the error I get when I run my spark streaming app on 2 node EC2 cluster, with 1 master and 1 worker. Works fine in local mode. Please help. Thanks
