> 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.
