Ayush Saxena commented on HDFS-15766:
-------------------------------------
Seems there is a change in {{TestRouterRpc.}}
{code:java}
verifyFileExists(routerFS, snapshotFolder + "/.snapshot/newsnap"));
// Cleanup
- routerProtocol.delete(mountPoint, true);
+ nnProtocol.delete(mountPoint, true);
}
{code}
Why do we need that, we did a mkdir using routerProtocol, the delete should
also work on that?

> MockResolver.getMountPoints() breaks the semantic of

> This is required by router federation rename. I found this bug when writing
> unit test for the rbf rename. Let's fix it here to avoid mixing up with the
> router federation rename.
