Unknown Health after restarting server in EC2


Unknown Health after restarting server in EC2


I installed a cluster using Cloudera Director in Amazon EC2.


The installation was successful. After I restart the EC2 machines, the cloudera manager --> hosts says "Unknown Health" for all the machines in the cluster.


The cloudera director also says  "Unknown health" for all the services and hosts


Is there any other service that needs to be started after sarting the instances?


Is there any manual configuration that needs to be done after installing using cloudera director.
