> *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.
