Hitesh Shah commented on YARN-2833:
-----------------------------------
[~zjshen] Please create a dup of this with the relevant info so that it is
considered for the v2 design. I will close this one out.
> Timeline Domains should be immutable by default

> Key: YARN-2833
> URL: https://issues.apache.org/jira/browse/YARN-2833
> Project: Hadoop YARN
> Issue Type: Bug
> Components: timelineserver
> Reporter: Hitesh Shah
>
> In a general sense, when ACLs are defined for applications in various orgs
> deploying Hadoop clusters, the ratio of unique ACLs to no. of jobs run on the
> cluster should likely be a low value. In such a situation, it makes sense to
> have a way to normalize the ACL set to generate an immutable domain id.
> This should likely have performance and storage benefits.
> There may be some cases where domains may need to be mutable. For that, I
> propose a flag to be set when the domain is being created ( flag's default
> value being immutable ).
