> The {{JobMaster}} should try reconnecting to the latest known resource manager leader
in case of a resource manager heartbeat timeout. Otherwise the {{JobMaster}} will only try
connecting to a {{ResourceManager}} if the leader address information change. In case of a
false positive heartbeat timeout, this could break the {{JobMaster's}} connection to the {{ResourceManager}}
permanently.
