can you put in your script if not too long. Perhaps there is something we can see.

In my script, I set the configs, add the services, hosts and components with the API. I also install HDP and persist the cluster in the same script. I start the services using the GUI. I am able to install all the services but YARN fails to start with this error: org.apache.hadoop.security.AccessControlException: Permission denied: user=yarn, access=WRITE, inode="/":hdfs:hdfs:drwxr-xr-x I am able to start it after I modify the permissions as hdfs user using the command hadoop fs -chmod 777 /, However, I do not see this issue if we install and start the services using the GUI. Is there any API call that I am missing that would handle this? Thanks, Ramya
