      • uriToString

        public static java.lang.String uriToString​( uri)
        From Apache Spark

        Convert URI to String. Since URI.toString does not decode the uri, e.g. change '%25' to '%'. Here we create a hadoop Path with the given URI, and rely on Path.toString to decode the uri

        uri - the URI of the path
        the String of the path
