> [YARN-7069] Limit format of resource type name
> ----------------------------------------------
>
> Key: YARN-7442
> URL: https://issues.apache.org/jira/browse/YARN-7442
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager, resourcemanager
> Reporter: Wangda Tan
> Assignee: Wangda Tan
> Priority: Blocker
>
> I think we should limit format of resource type name. Otherwise it could be
> very hard to update in the future after release.
> I propose to have format:
> {code}
> [a-zA-Z0-9][a-zA-Z0-9_.-/]*
> {code}
> Adding this check to setResourceInformation might affect performance a lot.
> Probably we can add to {{ResourceUtils#initializeResourcesMap}} when resource
> types are loaded from config file.
