Hi, If I forgot to stop collector before start a collector. Then I will get message the Collector.pid file can not be written. Then I can not stop collector by the command "sudo bin/chukwa collector stop". Because start twice will assign new PID and new port to collector. And the new PID is not written into the Collector.pid file. And I can not find the PID by the port because the port is not 8080. Does anyone meet the same problem ? And how to stop collector/agent in this situation?
Thanks
