Login in Azure as maria_dev, running tutorial and encountered the outofmemory issue, try to increase the tez containner size, but under that account it does not allow me to modify the configuration.
What should I do?
maria_dev is a read-only user on Ambari and doesn't have admin privileges. Please check this post to find out how to login as admin https://community.hortonworks.com/questions/27705/hortonworks-sandbox-dont-have-the-action-option-in... After that you will be able to manage your cluster, and change Tez container size.
The reason you are not able to change anything in there is you are logged in as maria_dev user which is readonly for sandbox 2.4
