Github user mengxr commented on the pull request: https://github.com/apache/spark/pull/304#issuecomment-39647746 The error message is > Job aborted: Task 0.0:0 failed 1 times (most recent failure: Exception failure in TID 0 on host localhost: java.lang.ClassCastException: org.apache.spark.mllib.regression.LabeledPoint cannot be cast to [Ljava.lang.Object;)" The tests runs fine on my local machine. Could it be a JVM issue?
