> New API for enclosing root path for a file
> ------------------------------------------

> Key: HDFS-16791
> URL: https://issues.apache.org/jira/browse/HDFS-16791
> Project: Hadoop HDFS
> Issue Type: Improvement
> 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
