Subject [jira] [Updated] (SPARK-23422) YarnShuffleIntegrationSuite failure when SPARK_PREPEND_CLASSES set to 1
Date Wed, 14 Feb 2018 12:53:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-23422?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gabor Somogyi updated SPARK-23422:
----------------------------------
    Description: 
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}
