Hi @iemejia, is the situation with Docker that if the Flink processes are
started as daemons and the script returns that Docker assumes the process has
terminated?
Skipping the pid file might work fine for a container where one wouldn't
start multiple TaskManagers but would cause logfile issues otherwise. We do
need to add locking to the pid file.
