I have created an EMR cluster (v5.35.0) and am trying to run a sample word_count.py to verify if I am able to execute a flink job. I am able to use python3 as mentioned in this question How do you run pyflink scripts on AWS EMR?
Using the below command to submit the job from /usr/lib/flink on the master node
flink run -m yarn-cluster --python examples/python/table/word_count.py
but I run into the following error
Executing word_count example with default input data set.
Use --input to specify file input.
Printing result to stdout. Use --output to specify output path.
Traceback (most recent call last):

I have choosen spark, hadoop, flink, presto, zookeeper as the frameworks. It works without a glitch if I use WordCount.jar but doesn't work for word_count.py
I am not sure why it shows that pyflink module is not found. I also installed apache flink again on the master node using pip as a last ditch effort but the same error occurs
pip install apache-flink==1.14
Any pointers would be helpful
Update 1:
I was able to solve this by getting help from AWS Support. They asked me to create a separate venv and install the dependencies. If you look into the yarn log file for that application id, you would also get the stacktrace.
