> For a given service if the theme.json file is not properly formatted, Ambari server will still start 'successfully' but attempts to add that service to the cluster will fail.
> The Ambari server start will log the theme error.  Although it neglects to mention which theme file and service are in error.
> When you attempt to add the service, it will query for the service's themes:
> api/v1/stacks/<stack>/versions/<version>/services?StackServices/service_name.in(HDFS,YARN,MAPREDUCE2,ZOOKEEPER,RANGER,RANGER_KMS,SLIDER)&themes/ThemeInfo/default=true&fields=themes/*
> This will return something like the following for the invalid theme:
>          "ThemeInfo" : {
>            "default" : true,
>            "file_name" : "theme_version_2.json",
>            "service_name" : "RANGER_KMS",
>            "stack_name" : "BigInsights",
>            "stack_version" : "4.3",
>            "theme_data" : null
>          }
> where the theme_data is null.
