Key: FLINK-26171
URL: https://issues.apache.org/jira/browse/FLINK-26171
Project: Flink
Issue Type: Bug
Components: API / Python
Affects Versions: 1.14.3
Reporter: Xuannan Su
It seems that when submitting a pyFlink job with the `flink run` command, the
-py option has issues with a path that start with double slash "//".
You can reproduce the problem with the wordcount python example.
{code:bash}
# Job successfully submitted
./bin/flink run -py "${PWD}"/examples/python/datastream/word_count.py
Job has been submitted with JobID 54ab79a32b4e441ee80bda92be7cb547
# Fail to submit the job if the path start with double slash
./bin/flink run -py /"${PWD}"/examples/python/datastream/word_count.py
