Description

In the managed cluster mode, the Gobblin Yarn Application Master joins Helix cluster in the ADMINISTRATOR role. However, Helix does not support messaging for instances which are not CONTROLLER or PARTICIPANT. To properly handle shutdown and token file update messages, the AppMaster should connect to the Helix cluster as a PARTICIPANT, these message types need to be destined to PARTICIPANT instead of CONTROLLER as is the case today.
