Hi All,
I've been experiencing a very strange error after upgrade from Spark 0.9 to
1.0 - it seems that saveAsTestFile function is throwing
java.lang.UnsupportedOperationException that I have never seen before.
Any hints appreciated.
scheduler.TaskSetManager: Loss was due to java.lang.ClassNotFoundException:
org.apache.spark.rdd.RDD$$anonfun$saveAsTextFile$1 [duplicate 45]
