Hi, I've setup a 5 node cluster using ambari using different machines - not virtualbox VMs. To begin with I've installed only HDFS and YARN (and their dependencies). MapReduce2 service is not starting - when I try to restart history server of mapreduce 2 service, I see this error: Traceback (most recent call last):

"message": "Failed to find datanode, suggest to check cluster health. excludeDatanodes=null"
}
} I've verified that the datanodes are running ok - Ambari reports that all the services are running ok What could be the problem? How do I remedy this situation? Update: I ran service check on HDFS and it fails, with the same error as above. Thanks, Radha.
