hi @StephanEwen, the cases in flink-filesystem-connector will fail first in
our building machine. I have go through the cases in flink-fs-tests, I think
they will fail too if I remove the change from the root pom. I think it is
better to set in the root pom, because the HadoopUtils is in the package
flink-java, and many modules have dependency on flink-java and users of the
utils may have no idea that the HadoopUtils have dependency on the environment
variables that will cause wired failures and it is hard to trace.
