Reading the data written to s3 by Amazon Kinesis Firehose stream

Question

I am writing record to Kinesis Firehose stream that is eventually written to a S3 file by Amazon Kinesis Firehose.

My record object looks like

ItemPurcha         


        

Answer 1

I also had the same problem, here is how I solved.

1. replace "}{" with "}\n{"

2. line split by "\n".

   input_json_rdd.map(lambda x : re.sub("}{", "}\n{", x, flags=re.UNICODE))
                 .flatMap(lambda line: line.split("\n"))
   

A nested json object has several "}"s, so split line by "}" doesn't solve the problem.
