> STR
> 1) Install Ambari-2.6.0.0-267
> 2) Stop All Services
> 3) Upgrade Ambari from 2.6.0.0-267 to 2.7.0.0-292
> 4) Upgrade Non Stack Services (Smartsense , Ambari Infra , Logsearch)
> 5) try to start all services.
> Cause - Livy for Spark2 Server Start operation tries to access namenode
> whereas Namenode start hasn't happened yet. Looks to be some issue with RCO
> sequence of operations. Hence all other operations are aborted.
