> When troubleshooting FLINK-15456, I noticed a TM hang in starting and not able to register to RM. However, there is no debug log on which host the TM located on and thus I can hardly find the logs of the problematic TM.
> I think we should print the host name when starting a TM, i.e. in this logs
> "TaskExecutor container_XXXX will be started ...".
> This would make it possible for us to troubleshoot similar problems. (not only for cases that TM hang in starting, but also for cases that TM exits in starting)
