Subject [jira] [Created] (YARN-7854) Attach prefixes to different type of node attributes
Date Tue, 30 Jan 2018 06:09:00 GMT
Weiwei Yang created YARN-7854:
---------------------------------

             Summary: Attach prefixes to different type of node attributes
                 Key: YARN-7854
                 URL: https://issues.apache.org/jira/browse/YARN-7854
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: RM
            Reporter: Weiwei Yang


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.
