Suresh Srinivas commented on HADOOP-7661:
-----------------------------------------
Can you please add javadoc to the FileSystem method indicating the distinction
between local file systems with no authority and remote file systems with
authority and the expected behavior. We should also consider annotating this
method as private in trunk.
> FileSystem.getCanonicalServiceName throws NPE for any file system uri that
> doesn't have an authority.
