> YarnShuffleIntegrationSuite fails when SPARK_PREPEND_CLASSES set to 1.
> Normally mllib built before yarn module. When SPARK_PREPEND_CLASSES used
> mllib classes are on yarn test classpath.
> Before 2.3 that did not cause issues. But 2.3 has SPARK-22450, which
> registered some mllib classes with the kryo serializer. Now it dies with the
> following error:
> {code:java}
> 18/02/13 07:33:29 INFO SparkContext: Starting job: collect at
> YarnShuffleIntegrationSuite.scala:143
> Exception in thread "dag-scheduler-event-loop"
> java.lang.NoClassDefFoundError: breeze/linalg/DenseMatrix
> {code}
