Matthias commented on FLINK-23611:
----------------------------------
Another piece that I still don't fully understand is an assert error provided
in the {{mvn-1.log}} of the 2nd build's artifacts:
{code}
22:44:46,572 [Frontend (CLI/YARN Client) runner thread (startWithArgs()).] INFO
org.apache.flink.yarn.YarnTestBase [] - Runner
stopped with exception
java.lang.AssertionError: The YARN session returned with unexpected value=1

{code}
It indicates that we endup in [this if condition in
