> On clusters which are large (1000's of hosts, 10's of 1000's of components), prior upgrades which have been finalized can cause problems when starting future upgrades:

> AMBARI-20672 partially fixes this by keeping the {{UpgradeEntity}} association in even during suspended upgrades. Therefore, a query against {{HostRoleCommandDAO}} isn't needed anymore. However, if an upgrade is in progress, we must still walk the upgrade to determine if the {{UpdateDesiredStackAction}} has been called yet. This calculation can be cached and invalidated to prevent the need to traverse a massive upgrade hierarchy.
