This downgrade must be completed before a new upgrade or downgrade can begin. And the stderr output: org.apache.ambari.server.AmbariException: The following 1 host component(s) have not been downgraded to their desired versions: host_a5: NODEMANAGER (current = 2.6.3.0-235, desired = 2.6.2.0-205) But this command from the ambari server returned: (https://community.hortonworks.com/questions/141083/hdp-262-upgrade-stuck.html) psql ambari -U ambari...
