------------------------------------

I moved the JIRA to HDFS-13891.
Do you mind rebasing the patch based on the branch and upload a patch with the proper naming for that?
Take also a look at that branch as we are already supporting GenericRefreshProtocol there.
This was added by HDFS-13856.

> RouterAdminServer should support RefreshUserMappingsProtocol , or a proxyuser client would be refused to impersonate.As shown in the screenshot
