Subject PySpark Nested Json Parsing
Date Mon, 20 Jul 2015 10:26:20 GMT
Hi,

I am new to Apache Spark. I am trying to parse nested json using pyspark.
Here is the code by which I am trying to parse Json.
I am using Apache Spark 1.2.0 version of cloudera CDH 5.3.2.

lines = sc.textFile(inputFile)

import json
def func(x):
json_str = json.loads(x)
if json_str['label']:
                if json_str['label']['label2']:
return (1,1)
return (0,1)

lines.map(func).reduceByKey(lambda a,b: a + b).saveAsTextFile(outputFile)

I am getting following error,
ERROR [Executor task launch worker-13] executor.Executor
(Logging.scala:logError(96)) - Exception in task 1.0 in stage 14.0 (TID 25)
