>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.1.2
>            Reporter: Jayush Luniya
>            Assignee: Jayush Luniya
>            Priority: Critical
>             Fix For: 2.1.3
>
>
> The following pre-req checks assume that {{fs.DefaultFS}} can only be a 
> {{*dfs}} protocol.
> {noformat}
>     
> <check>org.apache.ambari.server.checks.ServicesMapReduceDistributedCacheCheck</check>
>     
> <check>org.apache.ambari.server.checks.ServicesTezDistributedCacheCheck</check>
> {noformat}
> However, other DFS such as {{WASB}} and {{ECS}} are valid ones and RU can be 
> performed with these DFS.
> Upgrade packs should allow to declaratively define protocols that are 
> allowed. As an interim fix the checks can be modified to allow say 
> {{[*dfs|wasb|ecs]://}}
