Description

PROBLEM
JN wizard fails if there is an issue with the datanode start at the final step of the wizard when its suppose to bring up the services

DESCRIPTION
We had bad disks on a couple of DN and at the final state where the JN wizard was suppose to bring up all the services it failed with errors. After this the only option was to go ahead and cancel the wizard to proceed as the next tab was greyed out. This is a bad user experience.
