Hitesh Shah created YARN-2833: --------------------------------- Summary: 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 ). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
