I use spark 1.3.1 and Python 2.7 It is my first experience with Spark Streaming.
I try example of code, which reads data from file using spark streaming. This is link to example: https://github.com/apache/spark/blob/master/examples/src/main/python/streaming/hdfs_wordcount.py My code is the following: conf = (SparkConf() .setMaster("local") .setAppName("My app") .set("spark.executor.memory", "1g")) sc = SparkContext(conf = conf) ssc = StreamingContext(sc, 1) lines = ssc.textFileStream('../inputs/2.txt') counts = lines.flatMap(lambda line: line.split(" "))\ .map(lambda x: (x, 1))\ .reduceByKey(lambda a, b: a+b) counts.pprint() ssc.start() ssc.awaitTermination() content of 2.txt file is following: a1 b1 c1 d1 e1 f1 g1 a2 b2 c2 d2 e2 f2 g2 a3 b3 c3 d3 e3 f3 g3 I expect that something related to file content will be in console, but there are nothing. Nothing except text like this each second: ------------------------------------------- Time: 2015-09-03 15:08:18 ------------------------------------------- and Spark's logs. Do I do some thing wrong? Otherwise why it does not work? -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/Python-Spark-Streaming-example-with-textFileStream-does-not-work-Why-tp24579.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
