Description

1. Set the following configs to run nodeLabels test via Ambari Rest Call

 yarnProperties = {'yarn.acl.enable': 'true',
                      'yarn.node-labels.enabled' : "True",
                      'yarn.node-labels.fs-store.root-dir': NODE_LABEL_STORE_DIR,
                      'yarn.admin.acl': yarn_user + ',' + qa_user}

where NODE_LABEL_STORE_DIR = "/tmp/node-labels"
2Restart ResourceManager and NodeManagers via ambari
3. After running these commands, /tmp directory's permission changes to
[drwx------ - yarn hadoop] from [drwxrwxrwx - hdfs hadoop] causing other tests to fail since it cannot access /tmp
