* HADOOP-18249. Fix getUri() in HttpRequest has been deprecated.
WebHdfsHandler.java req.getUri() replace uri(), req.getMethod() replace method()
HostRestrictingAuthorizationFilterHandler.java req.getUri() replace uri()
TestHostRestrictingAuthorizationFilterHandler.java remove throws Exception, channelResponse.getStatus() replace status().
