registering Array of CompactBuffer to Kryo

[Andras Barjak]

Hi,

what is the correct scala code to register an Array of this private spark
class to Kryo?

"java.lang.IllegalArgumentException: Class is not registered:
org.apache.spark.util.collection.CompactBuffer[]
Note: To register this class use:
kryo.register(org.apache.spark.util.collection.CompactBuffer[].class);"

thanks,
