> Adding support for submitting PySpark based Sparks jobs (which is normally
> structured as modules) over Livy on existing "ExecuteSparkInteractive"
> processor.
> This is done by reading file paths for pyfiles and file and an option from
> user whether the processor should trigger a batch job or not.
> [https://livy.incubator.apache.org/docs/latest/rest-api.html]
> *Current Work flow Logic ( [https://github.com/apache/nifi/pull/2521
> )|https://github.com/apache/nifi/pull/2521]*
> * Check whether the processor has to handle code or submit a Spark job
> * Read incoming flow file
> ** If batch == true
> *** If flow file matches Livy `batches` JSON response through `wait` loop
> **** Wait for Status Check Interval
> **** Read the state
> **** If state is `running` route it to `wait` or if it is `success` or
> `dead` route it accordingly
> *** Else
> **** Ignore the flow file
> **** Trigger the Spark job over Livy `batches` endpoint
> **** Read the state of the submitted job
> **** If state is `running` route it to `wait` or if it is `success` or
> `dead` route it accordingly
> ** Else:
> *** Existing Logic to handle `Code`
