>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: fs
>    Affects Versions: 3.3.6
>            Reporter: Tom McCormick
>            Assignee: Tom McCormick
>            Priority: Major
>              Labels: pull-request-available

>
> At LinkedIn we run many HDFS volumes that are federated by either 
> ViewFilesystem or Router Based Federation. As our number of hdfs volumes 
> grows, we have a growing need to migrate data seemlessly across volumes.
> Many frameworks have a notion of staging or temp directories, but those 
> directories often live in random locations. We want an API getEnclosingRoot, 
> which provides the root path a file or dataset. 
> In ViewFilesystem / Router Based Federation, the enclosingRoot will be the 
> mount point.
> We will also take into account other restrictions for renames like 
> encryptions zones.
> If there are several paths (a mount point and an encryption zone), we will 
> return the longer path
