Hi Phil, thanks for the Jira, I will try to take a look asap.

I am currently trying a few code changes to see if I can squash this error. I have created https://issues.apache.org/jira/browse/SPARK-11193 to track progress, hope that is okay! In the meantime, can anyone confirm their ability to run the Kinesis-ASL example using Spark > 1.5.x ? Would be helpful to know if it works in some cases but not others. http://spark.apache.org/docs/1.5.1/streaming-kinesis-integration.html Thanks Phil On Thu, Oct 15, 2015 at 10:35 PM, Jean-Baptiste Onofré <j...@nanthrax.net <mailto:j...@nanthrax.net>> wrote: Hi Phil, sorry I didn't have time to investigate yesterday (I was on a couple of other Apache projects ;)). I will try to do it today. I keep you posted.

When reading the code https://github.com/apache/spark/blob/branch-1.5/streaming/src/main/scala/org/apache/spark/streaming/scheduler/ReceiverTracker.scala#L100 it looks like the receivers are definitely being ser/de. I think this is the issue, need to find a way to confirm that now... 2015-10-15 16:12 GMT+07:00 Eugen Cepoi <cepoi.eu...@gmail.com <mailto:cepoi.eu...@gmail.com> <mailto:cepoi.eu...@gmail.com <mailto:cepoi.eu...@gmail.com>>>: Hey, A quick update on other things that have been tested. When looking at the compiled code of the spark-streaming-kinesis-asl jar everything looks normal (there is a class that implements SyncMap and it is used inside the receiver). Starting a spark shell and using introspection to instantiate a receiver and check that blockIdToSeqNumRanges implements SyncMap works too. So obviously it has the correct type according to that. Another thing to test could be to do the same introspection stuff but inside a spark job to make sure it is not a problem in the way the jobs are run. The other idea would be that this is a problem related to ser/de. For example if the receiver was being serialized and then deserialized it could definitely happen depending on the lib used and its configuration that it just doesn't preserve the concrete type. So it would deserialize using the compile type instead of the runtime type.

Just a dumb question: did you update all, including the Spark Kinesis extra containing the KinesisReceiver ? I checked on tag v1.5.0, and at line 175 of the KinesisReceiver, we see: blockIdToSeqNumRanges.clear() which is a: private val blockIdToSeqNumRanges = new mutable.HashMap[StreamBlockId, SequenceNumberRanges] with mutable.SynchronizedMap[StreamBlockId, SequenceNumberRanges] So, it doesn't look fully correct to me. Let me investigate a bit this morning.
