Is the one that succeeded, running on the same host as the ambari-server? Perhaps there is no route to the server from the agents.

End of the day, Ambari calls yum install (or the equivalent zypper/apt) to install the hbase packages. Post install if you replace the jars or other libraries then it will be transparent to Ambari (e.g. in /usr/hdp/2.6.0.0-457/hbase/lib). Of course this means that if you do Add Host then the same steps have to repeated.

If you are using Ambari to deploy, you can do an blueprint export and then use that to deploy a new cluster.

UI seems to use existence of Secondary NameNode to determine if HA is enabled or not. A quick option would be to add SNN manually using curl again. curl -u admin:admin -H "X-Requested-By: ambari" -X POST http://localhost:8080/api/v1/clusters/c1/services/HDFS/components/SECONDARY_NAMENODE curl -u admin:admin -H "X-Requested-By: ambari" -X POST http://localhost:8080/api/v1/clusters/c1/hosts/c6401.ambari.apache.org/host_components/SECONDARY_NAMENODE Install it - curl -u admin:admin -H "X-Requested-By: ambari" -X PUT -d'{"RequestInfo":{"context":"Install SNN","operation_level":{"level":"HOST_COMPONENT","cluster_name":"c1","host_name":"c6401.ambari.apache.org","service_name":"HDFS"}},"Body":{"HostRoles":{"state":"INSTALLED"}}}' http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/hosts/c6401.ambari.apache.org/host_components/SECONDARY_NAMENODE?HostRoles/state=INIT You should be able to see the option to enable NN HA.

Likely, HA wizard is not showing because SecondaryNameNode is missing. How did it get deleted? Was the cluster deployed using blueprint or UI?

What was the original version and what did you upgrade to/downgrade from. Is there a backup of PXF folder under /var/lib/ambari-server - possibly leftover from upgrade or downgrade?
