             Summary: Slider View: Verify using slider-client if application name can be used
                 Key: AMBARI-7932
                 URL: https://issues.apache.org/jira/browse/AMBARI-7932
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 1.7.0
            Reporter: Antonenko Alexander
            Assignee: Antonenko Alexander
             Fix For: 1.7.0


Precondition:
1)Deploy Ambari
2)Prepare cluster for adding slider apps
3)Create slider view
4)Create some apps
5)Enable security

STR:
1)Prepare cluster for adding slider apps at secured cluster
https://github.com/apache/ambari/blob/5e5e715b6b15dffffe15418dfe5732835d24ef57/contrib/views/slider/docs/index.md
2)Add new slider view ( Manage Ambari->Views->Slider->) (example: slider)
3)Try Add slider app with same parameters as above in new view

Actual result:
Could not Add slider app with same parameters as above in new view. Have Error message at deploy step.
{code}
Error message: Application Instance dir already exists: hdfs://c6401.ambari.apache.org:8020/user/yarn/.slider/cluster/accumulo0
{code}

Expected result:
Could Add slider app with same parameters as above in new view. The files (/cluster/accumulo0...etc) will deleted automaticly after enabled security or HA.

*Or*

The sliders apps that are added before enabled security or HA are present at UI , that I could  delete it manually from UI and add once more at secured cluster.
