Description

While accessing below yarn rest end point with POST method type,

http://rm_ip:8088/app/v1/services

below error is coming in non-secure cluster.

{
"diagnostics": "Null user"
}

When user.name is provided as query param with dr.who we can see that yarn started service with proxy user, not dr.who. 

In non-secure cluster, native service should ideally take the user from remote ugi.

in secure cluster, its better to derive user from kerberized shell.
