> As discussed in YARN-3359, we need to further identify timeline collectors' 
> creation order to rebuild collector discovery data in the RM. This JIRA 
> proposes to use <rm_timestamp, logical_version_number> to order collectors 
> for each application in the RM. This timestamp can then be used when a 
> standby RM becomes active and rebuild collector discovery data.
