Created ‎01-04-2017 02:16 PM

I am using this python code for word count that I got from the online lessons I am following but I am not able to run in my environment , getting errors shown below :

[sami@hadoop1 ~]$ more wordcount.py
from operator import add
from pyspark import SparkConf, SparkContext
import collections
from pyspark import SparkConf, SparkContext
import collections
conf = SparkConf().setMaster("local").setAppName("MyWordCount")
sc = SparkContext(conf = conf)
lines = sc.textFile("/user/sami/WC.txt").map(lambda x: x.split(' ')).reduceByKey(add)
output = lines.collect()
for (word, count) in output:
        print str(word) +": "+ str(count)

getting the following error 

[sami@hadoop1 ~]$ spark-submit wordcount.py
SPARK_MAJOR_VERSION is set to 2, using Spark2

@Sami Ahmad

Below is the simple wordcount example from Spark docs and this should work with both Spark 1.6.x and Spark 2.x.

>>> textFile = sc.textFile("file:///etc/passwd")
>>> wordCounts = textFile.flatMap(lambda line: line.split()).map(lambda word: (word, 1)).reduceByKey(lambda a, b: a+b)
>>> wordCounts.collect()

Ref: http://spark.apache.org/docs/latest/quick-start.html#more-on-rdd-operations

Hope this helps.

Below is the simple wordcount example from Spark docs and this should work with both Spark 1.6.x and Spark 2.x.

>>> textFile = sc.textFile("file:///etc/passwd")
>>> wordCounts = textFile.flatMap(lambda line: line.split()).map(lambda word: (word, 1)).reduceByKey(lambda a, b: a+b)
>>> wordCounts.collect()

Ref: http://spark.apache.org/docs/latest/quick-start.html#more-on-rdd-operations

Hope this helps.
