-----------------------------
Summary: Support NodeLabelsProvider at Resource Manager side
Key: YARN-3964
URL: https://issues.apache.org/jira/browse/YARN-3964
Project: Hadoop YARN
Issue Type: Task
Reporter: Dian Fu
Currently, CLI/REST API is provided in Resource Manager to allow users to
specify labels for nodes. For labels which may change over time, users will
have to start a cron job to update the labels. This has the following
limitations:
- The cron job needs to be run in the YARN admin user.
- This makes it a little complicate to maintain as users will have to make sure
this service/daemon is alive.
Adding a Node Labels Provider in Resource Manager will provide user more
flexibility.
