Atlas client was not installed on the Falcon Server. After installing the atlas client I can now access the Falcon Web UI. Thank you!

when the cluster and falcon were installed it did not have the Berkeley DB
installed. After searching my error messages I found that this was needed and
installed it using the steps outlined in this post: https://community.hortonworks.com/questions/11862/falcon-ui-not-working.html But
after installing the Berkeley DB I still have the same error. I have also tried
deleting the Falcon service in Ambari, redoing the steps to install Berkeley
DB, and then re-installing Falcon, but the same error remains.
