Subject [jira] [Updated] (YARN-3955) Support for priority ACLs in CapacityScheduler
Date Thu, 10 Nov 2016 17:29:58 GMT

Sunil G updated YARN-3955:
    Attachment: YARN-3955.0001.patch

Thanks [~jianhe] for the comments.

bq.I think readLock is not needed, the field itself is not changing
{{priorityACLs}} could be changed during reinitialize. Do we need to consider this point.
Also we may add REST based support to add ACLs during runtime. If reinitialize is fine, i
could remove lock and add it when REST is in progress. Thoughts?

> Support will be added for User-level access permission to use different application-priorities.
This is to avoid situations where all users try running max priority in the cluster and thus
degrading the value of priorities.
> Access Control Lists can be set per priority level within each queue. Below is an example
configuration that can be added in capacity scheduler configuration
> file for each Queue level.
> yarn.scheduler.capacity.root.<queue_name>.<priority>.acl=user1,user2
