Brock Noland commented on HIVE-7614:
------------------------------------
Three solutions discussed in HIVE-7540:
# Convert rows on read from HDFS into "HiveBytesWritable" which is serializable
# Use Kryo for serialization of closures
# Add writeObject/readObject methods to classes which will hold Writables
> Find solution for closures containing writables
> -----------------------------------------------

> HIVE-7540 performed a workaround so we could serialize closures with
> Writables. However, we need a long term solution.
