> Install a cluster with ZK+AMS services only. Then add HDFS service using the
> add-service wizard. In the configurations step, enter the value of 'NameNode
> directories' to '/home/foo' which should generate the validation error
> {{Can't start with "home(s)"}}.
> Now switch to configs of all other services and go back to HDFS configs. Now
> the textarea is not shown.
> Workaround: Hit _Back_ followed by _Next_ to show the text-area. OR just
> refresh the page to repopulate the configs.
