3. Create a word_count.py file to achieve word frequency statistics import osimport shutilfrom pyspark import SparkContextinputpath = 'input'outputpath =' result'sc = SparkContext ('local',' wordcount') # read the file input = sc.textFile (inputpath) # syncopate the word words = input.flatMap (lambda line: line.split (')) # convert and count counts = words.map (lambda word: (word, 1)) .reduceByKey (lambda x Y: X + y) # output result counts.foreach (print) # Delete the output directory if os.path.exists (outputpath): shutil.rmtree (outputpath, True) # write the statistical results to the result file counts.saveAsTextFile (outputpath)
Run the program and the result is as follows:
The statistical results are also saved in the part-00000 file in the result directory:
