> In FileSystem.get(uri, conf), it first creates a cache key from the uri and the conf
and then lookups the corresponding FileSystem object in the cache.  If the object is not found,
it initializes a FileSystem object and put it to the cache with the key.  However, during
FileSystem creation, the conf might be modified.  In such case, the key should be updated
before putting it to the cache.
