Thanks @zhengchenyu for your review and comment. This a draft PR related to
[PR4311](https://github.com/apache/hadoop/pull/4311). I'm not following
[HDFS-13522](https://issues.apache.org/jira/browse/HDFS-13522).002.patch, and I
will read it carefully.
Client -> RBF -> NameNode.
Whether RBF proxies the read request to the Observer should have nothing to
do with the Client.
