Thanks for your reply. Wordcount is only my simple test. In my case, I just
want to wrap some configuration into a XX.conf file and flink code to read from
the file to get the key-value map. I used to use '--files ' in spark job for
such case. So -yt in flink job can't support such case?
env.readTextFile(params.get("input")) This is the only line in my code.
