How can I somehow run spark.something in a worker? - rdd foreach spark.context

[alexgv12]

i am using rdd to parallelize a function, in this function i format the record i want to save, how can i store from this function the record with a dataframe? because every time i use spark..... an error is generated Caused by: org.apache.spark.api.python.PythonException: 'RuntimeError: SparkContext should only be created and accessed on the driver.'

How can I somehow run spark. something in a worker?

You cannot. It is not serializable and not available on a worker. I would recommend that you use the DataFrame APIs. It should be much more performant and there are very limited reasons why RDDs should be used over a DataFrame. Your function looks like it could be converted to a user defined function.
