Can you please share exactly which alert are you getting?
Or if you can share the ambari-alerts.log and also let us know that on host C what all components were installed?

ambari-agent Distro/conf select versions alert

If you are getting the alert with this message "Ambari Agent Distro/Conf Select Versions" then please check your "/usr/hdp" directory contents in working and non working hosts. You are not supposed to have any extra file or directory inside this directory created by your own apart from the one that comes with HDP installation.
In general this host-level alert is triggered if the distro selector such as hdp-select cannot calculate versions available on this host. This may indicate that /usr/$stack/ directory has links/dirs that do not belong inside of it.
For some versions of ambari this was reported as an issue: https://issues.apache.org/jira/browse/AMBARI-20648

hdp-select versions also returns single version.
[root@node1 hdp]# hdp-select versions 2.6.4.0-91 [root@node1 hdp]#
How this issue can be resolved to resolve the critical warnings during express upgrade?..
