Till Rohrmann commented on FLINK-22139:
---------------------------------------
What is the side pod? Could you try deploying a non-HA cluster as described in
the documentation and then log into the container of the {{JobManager}} and
check whether {{/opt/flink/log}} contains the log file?
> Flink Jobmanager & Task Manger logs are not writing to the logs files
