Thanks, Ying Zhang, for the patch. I can see that the new docs are styled after the add/modify docs, but it would be really nice to have docs that are reader-friendly.
For example, instead of "Remove cluster node labels: Executing yarn rmadmin -removeFromClusterNodeLabels "<label1,label2,label3>" (label splitted by ",") to remove node labels.", it would be nice to be a bit more readable, such as "To remove one or more node labels, execute the following command: yarn rmadmin -removeFromClusterNodeLabels "<label>[,<label>,...]". The command argument should be a comma-separated list of node labels to remove."
The rest of the bullets in the new docs can be made similarly more friendly by making them text instead of terse bullets.
