Errata for Spark for Java Developers

Here are all known errors or updates since the course was recorded. Please suggest an errata entry if your problem isn't listed here.

  • When running sqrtRDD.foreach(System.out::println) if you get a "not serializable" exception. We have added an update video to the course to explain the problem - as an easy workaround you can just add a .collect(); eg sqrtRdd.collect().forEach(System.out::println). (Not the capital E on Each).
