Subject [jira] [Created] (AMBARI-13341) Ambari refuses stack upgrade without NN HA and other requirements
Date Wed, 07 Oct 2015 15:52:26 GMT
Hari Sekhon created AMBARI-13341:
------------------------------------

             Summary: Ambari refuses stack upgrade without NN HA and other requirements
                 Key: AMBARI-13341
                 URL: https://issues.apache.org/jira/browse/AMBARI-13341
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
    Affects Versions: 2.1.0
         Environment: HDP 2.2
            Reporter: Hari Sekhon


Ambari refuses to upgrade HDP 2.2 stack => 2.3 for a cluster not running NN HA among other
things - which is very inconvenient for small test clusters  as NN HA can't be deployed with
less than 3 nodes for ZK quorum, blocking the upgrade entirely. Ambari should be able to ignore
this and just do the upgrade anyway. In fact, better yet, do a faster upgrade as per AMBARI-11098.
