Description

HDFS-2856 adds support that Datanodes don't require root or jsvc. If dfs.data.transfer.protection is configured and dfs.http.policy is HTTPS_ONLY, then secure dataNode doesn't need to use privileged port.

This has not been updated in the latest user doc of secure mode. This JIRA is to fix that.
