All the datanodes nodes in cluster found below an error and could not contacted to cluster after installed cdh 5.9.0 on ubuntu.
"Error, CM server guid updated, expected 85587073-270d-43d9-a44a-e213d9f7e45b, received 4c1402a5-8364-4598-a382-0c760710e897"

Got the same issue on my newly installed 5.9 version cluster.
Fixed it by deleting /var/lib/cloudera-scm-agent/cm_guid on each node.
