--------------------------------
[~mr.wang] ,yes ,{color:#2a2b2e}chinese. Ranger just can be able to configure
yarn access without to configure about timelineserver. As i konwn yarn on
ranger just be related to control access to user queue.
.And{color}{color:#2a2b2e} my ranger product environment doesn't configure any
yarn access. I'm sure the users running task have enough permission to access
such as queue. No any exceptions or errors about permissions occured on
rm,nm,timeserver server backgroud logs.{color}
