      Description

      HDFS-7541 added upgrade domain and HDFS-7877 added maintenance mode. Existing documentation about these two features are scarce and the implementation have evolved from the original design doc. Looking at code and Javadoc and I still don't quite get how I can get datanodes into maintenance mode/ set up a upgrade domain.

      File this jira to propose that we write an up-to-date description of these two features.
