> Key: YARN-9663
> URL: https://issues.apache.org/jira/browse/YARN-9663
> Project: Hadoop YARN

> ApplicationId represents the globally unique identifier for an application.
> The globally unique nature of the identifier is achieved by using the cluster timestamp. i.e. start-time of the ResourceManager along with a monotonically increasing counter for the application.
> But in yarn federation, the applicationId will be duplicated if the timestamp of subClusters is same.
> Shall we add clusterId in applicationId, like application_cluseterId_timestamp_xxx1
