-----------------------------------
Summary: Spark 1.5+ Kinesis Streaming - ClassCastException when
starting KinesisReceiver
Key: SPARK-11193
URL: https://issues.apache.org/jira/browse/SPARK-11193
Project: Spark
Issue Type: Bug
Components: Streaming
Affects Versions: 1.5.1, 1.5.0
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
