> Users could execute PyFlink jobs in YARN application mode as following:
> {code}
> ./bin/flink run-application -t yarn-application \
>       -Djobmanager.memory.process.size=1024m \
>       -Dtaskmanager.memory.process.size=1024m \
>       -Dyarn.application.name=<ApplicationName> \
>       -Dyarn.ship-files=/path/to/shipfiles \
>       -pyarch shipfiles/venv.zip \
>       -pyclientexec venv.zip/venv/bin/python3 \
>       -pyexec venv.zip/venv/bin/python3 \
>       -py shipfiles/word_count.py
> {code}
> In the above case, venv.zip will be distributed to the TMs via Flink blob server. However, blob server doesn't support files with size exceeding of 2GB. See https://github.com/apache/flink/blob/ea52732dc48a4f1c5be0925890cd8aa1ea2a11ed/flink-runtime/src/main/java/org/apache/flink/runtime/blob/BlobServerConnection.java#L223 for more details. This is very serious problem as Python users usually tend to install a lot Python libraries inside the venv.zip and some Python libraries are very large.
