[SPARK-23422][Core] YarnShuffleIntegrationSuite fix when SPARK_PREPENâ¦
â¦D_CLASSES set to 1
## What changes were proposed in this pull request?
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:
`
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
`
In this PR NoClassDefFoundError caught only in case of testing and then do
nothing.
## How was this patch tested?
