1. When I used the image http://savanna-files.mirantis.com/savanna-0.2-vanilla-1.1.2 image , the instances are active and I can SSh into them but the cluster turns into 'ERROR' state. Savanna/api-log has the following: >error during command execution "sudo chown -R $USER:$USER /opt/oozie/conf" >Return code 1 >chown: cannot access ' /opt/oozie/conf': No such file or directory and at the ending of the logs I can see the following error : >cluster creating fails with exception :'NoneType'object has no attribute 'name'
