Zhu Zhu created FLINK-15499:
-------------------------------
Summary: 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
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)
