>                 Key: YARN-7854
>                 URL: https://issues.apache.org/jira/browse/YARN-7854
>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: RM
>            Reporter: Weiwei Yang
>            Assignee: LiangYe
>            Priority: Major
> There are multiple types of node attributes depending on which source it comes from,
>  # Centralized: attributes set by users (admin or normal users)
>  # Distributed: attributes collected by a certain attribute provider on each NM
>  # System: some built-in attributes in yarn, set by yarn internal components, e.g scheduler
> To better manage these attributes, we introduce the prefix (namespace) concept to the
an attribute. This Jira is opened to figure out how to attach prefixes (automatically/implicitly
or explicitly) to different type of attributes.
