Apache Spark commented on SPARK-4877: ------------------------------------- User 'stephenh' has created a pull request for this issue: https://github.com/apache/spark/pull/3725 > userClassPathFirst doesn't handle user classes inheriting from parent > --------------------------------------------------------------------- > > Key: SPARK-4877 > URL: https://issues.apache.org/jira/browse/SPARK-4877 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 1.2.0 > Reporter: Stephen Haberman > > We're trying out userClassPathFirst. > To do so, we make an uberjar that does not contain Spark or Scala classes > (because we want those to load from the parent classloader, otherwise we'll > get errors like scala.Function0 != scala.Function0 since they'd load from > different class loaders). > (Tangentially, some isolation classloaders like Jetty whitelist certain > packages, like spark/* and scala/*, to only come from the parent classloader, > so that technically if the user still messes up and leaks the Scala/Spark > jars into their uberjar, it won't blow up; this would be a good enhancement, > I think.) > Anyway, we have a custom Kryo registrar, which ships in our uberjar, but > since it "extends spark.KryoRegistrator", which is not in our uberjar, we get > a ClassNotFoundException. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
