Summary: Ambari overrides user/groups settings configured by
cluster admins
Key: AMBARI-8940
URL: https://issues.apache.org/jira/browse/AMBARI-8940
Project: Ambari
Issue Type: Bug
Reporter: Andrew Onischuk
Assignee: Andrew Onischuk
Fix For: 2.1.0
Seen at Altiscale who were trying to use YARN with docker on an Ambari
deployed cluster.
Docker requires users to be in the "docker" group to be able to launch docker
containers. As a result, the user "yarn", which Ambari creates and adds to the
"hadoop" group, was changed to belong to both the "docker" and "hadoop"
groups.
However, after making this change on all nodes, we noticed that the the yarn
user was being removed from the docker group.
