私は、Apacheカフカを実装しようとの統合 ストリーミングスパークしていますここに私のpythonのコードは次のとおりです。
from __future__ import print_function
import sys
from pyspark.streaming import StreamingContext
from pyspark import SparkContext,SparkConf
from pyspark.streaming.kafka import KafkaUtils
if __name__ == "__main__":
#conf = SparkConf().setAppName("Kafka-Spark").setMaster("spark://127.0.0.1:7077")
conf = SparkConf().setAppName("Kafka-Spark")
#sc = SparkContext(appName="KafkaSpark")
sc = SparkContext(conf=conf)
stream=StreamingContext(sc,1)
map1={'demo':1}
kafkaStream = KafkaUtils.createStream(stream, 'localhost:2181', "test-consumer-group", map1)
# kafkaStream = KafkaUtils.createStream(stream, 'localhost:2181', "name", map1) #tried with localhost:2181 too
lines = kafkaStream.map(lambda x: x[1])
counts = lines.flatMap(lambda line: line.split(" "))
.map(lambda word: (word, 1)) \
.reduceByKey(lambda a, b: a+b)
counts.pprint()
stream.start()
stream.awaitTermination()
