[GitHub] [flink] rmetzger opened a new pull request #13757: [FLINK-18117][e2e] Add debugging information for hadoop startup
rmetzger opened a new pull request #13757:
URL: https://github.com/apache/flink/pull/13757
## What is the purpose of the change
This adds some non-invasive environment debugging to understand why the namenode can not allocate the http port inside a docker container.
I was not able to reproduce the failing e2e test.

Review comment:
Just as a side-note: I usually added also `-e` as a parameter getting "extended" output. Not sure whether it helps in that case but it's just nice to read for someone who knows German: `netstat -tulpen` 😄

Review comment:
Are you sure that you want to use `sudo -E sudo #...`? I couldn't test it quickly but it looks strange.

Review comment:
I tried the -e argument, but it only adds things like "package count" per port, which is not relevant for understanding who's allocating the port. (I copy pasted "tulpn" from somewhere, and also remembered the -e)
