示例1: SparkContext

outputFilename = argv[2]
fileUtil = FileUtil(sc)
workflow = Workflow(sc)
contextUrl = "https://raw.githubusercontent.com/american-art/aac-alignment/master/karma-context.json"
#1. Read the input
#test big file
inputRDD = workflow.batch_read_csv(inputFilename).partitionBy(1)
#test small file
# inputRDD = workflow.batch_read_csv(inputFilename)
#2. Apply the karma Model
outputRDD = workflow.run_karma(inputRDD,
