---------------------------------
[~xintongsong] would you help to confirm if it is really a problem?
> No debug log describes the host of a TM before any task is deployed to it in
> YARN mode

> Key: FLINK-15499
> URL: https://issues.apache.org/jira/browse/FLINK-15499
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / YARN
> Affects Versions: 1.10.0
> Reporter: Zhu Zhu
> Priority: Major
>
> When troubleshooting FLINK-15456, I noticed a TM hang in starting and not
> able to register to RM. However, there is no info on which host the TM
> located on and thus we 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)
