Spark: Executing the python kinesis streaming example

Question

I'm (very) new to spark, so apologies if this is a stupid question.

I am trying to execute the spark (2.2.0) python spark streaming example, however I keep running into the issue below:

Traceback (most recent call last):
  File "/Users/rmanoch/Downloads/spark-2.2.0-bin-hadoop2.7/kinesis_wordcount_asl.py", line 76, in <module>

The tarball I downloaded from spark's website did not include the external folder in it (seems like there's some license issue), so this is the command I have been trying to execute (after downloading kinesis_wordcount_asl.py from github)

bin/spark-submit --packages org.apache.spark:spark-streaming-kinesis-asl_2.11:2.2.0 kinesis_wordcount_asl.py sparkEnrichedDev relay-enriched-dev https://kinesis.us-west-2.amazonaws.com us-west-2

Happy to provide any additional details if needed.

Answer 1

Based on the exception it looks like there is a version mismatch between core Spark / Spark streaming and spark-kinesis. API changed between Spark 2.1 and 2.2 (SPARK-19405) and version mismatch would cause a similar error.

This makes me think you're submitting using incorrect binaries (just a guess) - it can be PATH, PYTHONPATH or SPARK_HOME issue if you use local mode. Because you get signature mismatch we can assume that spark-kinesis is loaded correctly and org.apache.spark.streaming.kinesis.KinesisUtilsPythonHelper is present on the CLASSPATH.
