Spark topology is generally YARN (again because of Amazon EMR) but I have also tried standalone.

The exact command I built with was
{noformat}
spark git:(4f894dd) $ mvn -Pyarn -Pkinesis-asl -Phadoop-2.6 -DskipTests clean package
{noformat}

Have also tried the following:
{noformat}
mvn -Pyarn -Pkinesis-asl -Phadoop-2.2 -DskipTests clean package
{noformat}

{noformat}
mvn -Pyarn -Pkinesis-asl -Phadoop-2.2 -DskipTests clean package
{noformat}

{noformat}
./dev/change-scala-version.sh 2.11
mvn -Pyarn -Phadoop-2.6 -Dscala-2.11 -Pkinesis-asl -DskipTests clean package
{noformat}

> 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 https://kinesis.us-east-1.amazonaws.com
