----------------------------------------------
It looks to work fine to me:

> Key: SPARK-11193
> URL: https://issues.apache.org/jira/browse/SPARK-11193
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.5.0, 1.5.1
> Reporter: Phil Kallos
>
> After upgrading from Spark 1.4.x -> 1.5.x, I am now unable to start a Kinesis
> Spark Streaming application, and am being consistently greeted with this
> exception:
> java.lang.ClassCastException: scala.collection.mutable.HashMap cannot be cast
> to scala.collection.mutable.SynchronizedMap

> Worth noting that I am able to reproduce this issue locally, and also on
> Amazon EMR (using the latest emr-release 4.1.0 which packages Spark 1.5.0).
> Also, I am not able to run the included kinesis-asl example.
> Built locally using:
> git checkout v1.5.1
> mvn -Pyarn -Pkinesis-asl -Phadoop-2.6 -DskipTests clean package
> Example run command:
> bin/run-example streaming.KinesisWordCountASL phibit-test kinesis-connector
