Description

ViewFileSystem incorrectly returns the FileSystem default values for getDefaultBlockSize() and getDefaultReplication(). This causes files to be created with incorrect values. The problem is that the current apis are insufficient for viewfs because the defaults depend on the underlying mount point. These methods need counterparts that accept a Path so viewfs can resolve the mount point for a path.
