> 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.
