Subject Spark kryo serialization register Datatype[]
Date Wed, 21 Dec 2016 13:49:33 GMT
To force spark to use kryo serialization I set
spark.kryo.registrationRequired to true.

Now spark complains that: Class is not registered:
org.apache.spark.sql.types.DataType[] is not registered.
How can I fix this? So far I could not successfully register this class.
