Description
With ACL enabled (https://issues.apache.org/jira/browse/LIVY-348), users that do not have view access should not be able to see others' jobs even at the listing page. Referencing yarn: https://issues.apache.org/jira/browse/YARN-7157
However, users are able to see the other users' sessions at the UI page, although they are unable to navigate in to see more details.
The sessions should be filtered before sending the list to the UI.
