Description

Currently any changes to add/delete a new proxy user requires DN restart requiring a downtime. This jira proposes to make the changes in proxy/user configuration reconfiguration via that ReconfigurationProtocol so that the changes can take effect without a DN restart. For details please refer https://hadoop.apache.org/docs/r2.8.0/hadoop-project-dist/hadoop-common/Superusers.html.
