             Summary: Slider View: Creating apps with default user (yarn) wont work on secured HDP cluster
                 Key: AMBARI-8012
                 URL: https://issues.apache.org/jira/browse/AMBARI-8012
             Project: Ambari
          Issue Type: Bug
          Components: contrib
    Affects Versions: 1.7.0
            Reporter: Srimanth Gunturi
            Assignee: Srimanth Gunturi
            Priority: Critical
             Fix For: 1.7.0


According to docs
https://github.com/apache/ambari/blob/5e5e715b6b15dffffe15418dfe5732835d24ef57/contrib/views/slider/docs/index.md
Slider user has to be present on all the hosts and needs to have a uid > 1000
"We shall assume the user as slider-user. In a secured cluster this user has to actually exist on all the hosts. The user should also have an uid greater than 1000."

Default slider user is yarn in current release
In case of HDP cluster being deployed by Ambari yarn user is created by Ambari and does not have uuid > 1000
So in such cases, using the default user for slider apps will not work. This needs to be either documented or we need to make change in Ambari code to always create yarn user with uuid > 1000

Exact error given by Slider:
