Yes, I know that how python scripts are executed for the test is different.
Let me elaborate:
Since running the tests are quite costly in my laptop, I normally test my
changes executing them in a local instance of Flink 1.0.3, since this is less
taxing. Once I complete the changes, I run `mvn verify`. The problem is that
when I call `pyflink2.sh test_main.py utils.py, the module that I pass to the
test script, is ignored unless I use HDFS, in which case, everything works fine.
