When I run a job using spark2 jar, I then run a python job to report :Multiple sources found for csv (org.apache.spark.sql.execution.datasources.v2.csv.CSVDataSourceV2, org.apache.spark.sql.execution.datasources.csv.CSVFileFormat), please specify the fully qualified class name.
My python code is
df = self.spark.read.csv(full_data_file_path, header=False, schema=schema,sep=sep)
