Reporter: Nigel Jones
* Login to ambari admin/admin at http://sandbox.hortonworks.com:8080/
* Navigate to falcon/quick links/Falcon Web UI
* links to http://sandbox.hortonworks.com:15000/
* Error displayed "Failed to load data. Error: 400 Param user.name can't be
empty"
* Google java script reports error as " Failed to load resource: the server
responded with a status of 400 (Param user.name can't be empty)" on
http://sandbox.hortonworks.com:15000/api/entities/list/feed?fields=status
* Click on processes -> same error (goes to
http://sandbox.hortonworks.com:15000/index.html?type=process)
* Manually add user name ie go to
http://sandbox.hortonworks.com:15000/index.html?type=process&user.name=falcon
* 2 processes I have installed are now listed correctly. No errors
* Click on one (cleanseEmailProcess... from the HDP falcon samples)
* Same error from the get
* Re-add username ->
http://sandbox.hortonworks.com:15000/entity.html?type=PROCESS&id=cleanseEmailProcess&user.name=falcon
* Process definitions and dependencies now visible in list view or graph view.
However an error "Failed to load data. Error: 400 Bad Request" still occurs on
the page
In more detail...
The initial errors are simply a bad response from the server of the form

The cause may be bad setup in HDP 2.2, or user error.... but may require error
checking if so?
logs/config to be added
