Description

When using the SparkRunner and specifying Spark to use the 'KryoSerializer' as:

spark-submit --class org.apache.beam.examples.BugWithKryoOnSpark --master yarn --deploy-mode client --conf spark.serializer=org.apache.spark.serializer.KryoSerializer /tmp/kafka-sdk-beam-example-bundled-0.1.jar --runner=SparkRunner

We get an exception after 10 or 15 seconds:

Exception in thread "main" java.lang.RuntimeException: org.apache.spark.SparkException: Job aborted due to stage failure: Exception while getting task result: com.esotericsoftware.kryo.KryoException: Unable to find class: org.apache.beam.runners.core.metrics.MetricsContainerImpl$$Lambda$31/1875283985

But when using the SparkRunner and specifying Spark to use the 'JavaSerializer' as:

spark-submit --class org.apache.beam.examples.BugWithKryoOnSpark --master yarn --deploy-mode client --conf spark.serializer=org.apache.spark.serializer.JavaSerializer /tmp/kafka-sdk-beam-example-bundled-0.1.jar --runner=SparkRunner

The pipeline works correctly.

Our deployment consist of (CDH 5.14.2, Parcels) and Spark2

spark-submit --version

I have attached a sample maven project which read data from kafka (localhost) and just produce an echo of the incoming data to reproduce this bug, please refer to the README for the full Stacktrace and information of how to build the sample
