> 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, includes
> # 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.
