What's the reason of pyspark error, Failed to add file [some path] specified in 'spark.submit.pyFiles' to Python path??

I ran the pyspark source using synapse Rest api. And I sometimes get next error.

[error message : 'evalue' of response message]

Interpreter died:

error message:

/opt/spark/python/lib/pyspark.zip/pyspark/context.py:341: RuntimeWarning: Failed to add file [local:///opt/spark/python/lib/pyspark.zip] specified in 'spark.submit.pyFiles' to Python path:

Hello no_name,

Welcome to the MS Q&A platform.

As per the error message, it seems like an issue adding a file to the Python path when running your PySpark code using the Synapse REST API.

Can you please check if the file path exists or if there are any permission issues causing the issue?

also, check the pyspark version and see if it is compatible or not.

Thank you for your comment. That error happened at sometimes. I ran one pyspark program and the program handled specific table on DB. When the program handled some table, it worked well. But the program didn't work about some other table.

The difference between the error and the no error is only a handled table.

I am confused because same pyspark code cause the error as handling table.

@no_name Hello no_name,

Since you mentioned that the error only occurs when handling a specific table in your database, this issue could be related to the data in the table. It is possible that the data in the table is causing the PySpark program to fail. Please try to isolate the issue by running the PySpark program on a smaller subset of the data in the table.

Another possible reason could be related to the configuration of the Spark submit command. You can check the configuration of the Spark submit command to ensure that it is correctly configured to include the PySpark library in the Python path.

I hope this helps.
