Unable to Deserialize TreeMap<byte[], byte[]>

[poneill00]

Hey, I'm using Kryo to serialize a TreeMap<byte[],byte[]> (which is required when writing to HBaseTap with DynamicScheme).

Serialization seems to work, but I get the below error when DeSerializing
Caused by: com.esotericsoftware.kryo.KryoException: Unable to find class: �[B

This project is pretty out of date.

I would recommend looking at:

https://github.com/twitter/chill/tree/develop/chill-hadoop

Set this to be your serialization class:
https://github.com/twitter/chill/blob/develop/chill-hadoop/src/main/java/com/twitter/chill/hadoop/KryoSerialization.java

and use:
https://github.com/twitter/chill/blob/develop/chill-java/src/main/java/com/twitter/chill/config/ConfiguredInstantiator.java#L85

with:
https://github.com/twitter/chill/blob/develop/chill-hadoop/src/main/java/com/twitter/chill/hadoop/HadoopConfig.java

to set your instantiator (the class that creates new Kryo instances).
