> 1. There is a bug in ServiceComponentHostSummary.java since its constructor should not
be comparing against the string UKNOWN, but rather rely on ComponentInfo to determine which
components need to advertise a version. Also, the function haveAllComponentsFinishedAdvertisingVersion
should instead compare the size of all components that can advertise a version, and the subset
of those that have done so already.
> 2. ClusterImpl.java has a bug in transitionHostVersionState() when setting the state
to UPGRADING if the Host has exactly one Component with a version.
> 3. FinalizeUpgradeAction.java has redundant code now that AMBARI-9755 is in because the
call to transitionClusterVersion() will also take care of transitioning HostVersions from
INSTALLED->CURRENT for hosts that only have components that do not advertise a version.
> It is of the utmost importance to test these changes in the following scenarios:
> Host added during cluster install
> Host added after cluster install
> Host added after bits are distributed
> A Host may be added with either 0 services, only services that do not advertise a version,
or at least one service that advertises a version.
