> *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.
