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 ).
