Daniel Darabos commented on SPARK-2403:
---------------------------------------
I think DAGSchedulerActorSupervisor is supposed to kill the system when things
like this happen. I am not sure why that does not happen in this case.
I forgot to include the stack trace:
java.lang.IllegalArgumentException: Class is not registered:
scala.collection.immutable.Range
Note: To register this class use:
kryo.register(scala.collection.immutable.Range.class);

> Spark stuck when class is not registered with Kryo
> --------------------------------------------------
>
> Key: SPARK-2403
> URL: https://issues.apache.org/jira/browse/SPARK-2403
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.0.0
> Reporter: Daniel Darabos
>
> We are using Kryo and require registering classes. When trying to serialize
> something containing an unregistered class, Kryo will raise an exception.
> DAGScheduler.submitMissingTasks runs in the scheduler thread and checks if
> the contents of the task can be serialized by trying to serialize it:
> https://github.com/apache/spark/blob/v1.0.0/core/src/main/scala/org/apache/spark/scheduler/DAGScheduler.scala#L767
> It catches NotSerializableException and aborts the task with an error when
> this happens.
> The problem is, Kryo does not raise NotSerializableException for unregistered
> classes. It raises IllegalArgumentException instead. This exception is not
> caught and kills the scheduler thread. The application then hangs, waiting
> indefinitely for the job to finish.
> Catching IllegalArgumentException also is a quick fix. I'll send a pull
> request for it if you agree. Thanks!
