@Palash Dutta, The value of falcon.app.type is "falcon" by default. It is passed as a run time parameter while starting falcon server. In your falcon host you can run the below command and see "-Dfalcon.app.type=falcon" ps -ef | grep falcon The flow is like this. falcon_start.py -> service_start.py -> service-start.sh . The falcon_start.py passes "falcon" as the argument to service_start.py where falcon is the falcon.app.type. Attaching the snippet below of falcon_start.py service_start_cmd = os.path.join(base_dir, 'bin', 'service_start.py') subprocess.call(['python', service_start_cmd, 'falcon', other_args]) You can find these scripts under /usr/hdp/<hdp-version>/falcon/bin. Hope this helps. Thanks, Aditya ... View more
