It turned out to be a problem with `SerializationUtils` from Apache Commons Lang. There is an open issue where the class will throw a `ClassNotFoundException` even if the class is in the classpath in a multiple-classloader environment: https://issues.apache.org/jira/browse/LANG-1049
We moved away from the library and our Spark job is working fine now. The issue was not related with Spark finally. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/ClassNotFoundException-even-if-class-is-present-in-Jarfile-tp25254p25268.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
