Hi al,

I have set up a 3 node Cloudera 5.14 cluster on Azure with Ubuntu 14 machines and there seems an issue when I start the cluster.

If I shutdown the Azure instances for the day and start the Azure instances next morning and when I try to start the cloudera cluster, all services are getting up except name node. The name node is not starting up and shows the error message " the name node is not formatted". The work aroud I do is format the name node every morning (yes, it is a test cluster) and do the rest of the job. Any clue what is going wrong?

STARTUP_MSG:   java = 1.7.0_67
