Stop the Falcon server and, if installed, the Prism server:

su - falcon -c "/usr/hdp/current/falcon-server/bin/falcon-stop"

su - falcon -c "/usr/hdp/current/falcon-server/bin/prism-stop"

Switch to the previous Falcon version:

hdp-select set falcon-server 2.2.0.0-2041

Start the Falcon server and, if installed, the Prism server:

su - falcon -c "/usr/hdp/current/falcon-server/bin/falcon-start"

su - falcon -c "/usr/hdp/current/falcon-server/bin/prism-start"

Check the status of the server. The following command should return status and port number:

su - falcon ./bin/falcon-status

Run the falcon smoke tests listed in Appendix A, and perform additional validation if necessary.
