> NullPointerException using checkpointed mapWithState with KryoSerializer
> ------------------------------------------------------------------------
>
> Key: SPARK-12591
> URL: https://issues.apache.org/jira/browse/SPARK-12591
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.6.0
> Environment: MacOSX
> Java(TM) SE Runtime Environment (build 1.8.0_20-ea-b17)
> Reporter: Jan Uyttenhove
>
> Issue occured after upgrading to the RC4 of Spark (streaming) 1.6.0 to
> (re)test the new mapWithState API, after previously reporting issue
> SPARK-11932 (https://issues.apache.org/jira/browse/SPARK-11932).
> For initial report, see
> http://apache-spark-developers-list.1001551.n3.nabble.com/Spark-streaming-1-6-0-RC4-NullPointerException-using-mapWithState-tt15830.html
> Narrowed it down to an issue unrelated to Kafka directstream, but, after
> observing very unpredictable behavior as a result of changes to the Kafka
> messages format, it seems to be related to KryoSerialization in specific.
> For test case, see my modified version of the StatefulNetworkWordCount
> example: https://gist.github.com/juyttenh/9b4a4103699a7d5f698f
> To reproduce, use RC4 of Spark-1.6.0 and
> - start nc:
> {code}nc -lk 9999{code}
> - execute the supplied test case:
> {code}bin/spark-submit --class
> org.apache.spark.examples.streaming.StatefulNetworkWordCount --master
> local[2] file:///some-assembly-jar localhost 9999{code}
> Error scenario:
> - put some text in the nc console with the job running, and observe correct
> functioning of the word count
> - kill the spark job
> - add some more text in the nc console (with the job not running)
> - restart the spark job and observe the NPE
> (you might need to repeat this a couple of times to trigger the exception)
> Here's the stacktrace:
> {code}
