Íñigo Goiri commented on HDFS-15535:
------------------------------------
Yes, makes sense to cast both, either one is fine with me.
I guess he most consistent one is to do the cast outside for both.
{code}
@SuppressWarnings("unchecked")
T loc = (T)location;
@SuppressWarnings("unchecked")
R ret = (R) result;
return new RemoteResult<>(loc, ret);
{code}
I'm fine either way.

> Presently, after invoking {{createSnapshot}} and {{getSnapshotListing}}, the
> namespace path is replaced with mount path.
> This presumes as of now that, the invokedLocation shall always be the first
> one in the sequence, but there are multiple reasons, where the directory
> might not be in the first location.
> So, rather than replacing using firstLocation, we should replace path using
> actual invoked Location.
