Description

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.
