TestUnsafeByteArrayOutputStream tests both input and output streams. I have
added more testing in next PR through kryo serialization.

> Key: GIRAPH-1181
> URL: https://issues.apache.org/jira/browse/GIRAPH-1181
> Project: Giraph
> Issue Type: Improvement
> Reporter: Yuksel Akinci
> Priority: Major
>
> Adding a new stream type which extends from
> com.esotericsoftware.kryo.io.Input/Output, so that it can be used with kryo
> serializer. It improves the performance of kryo by faster read/writes (unsafe
> IO), and also eliminates the need for interim buffers to convert from
> DataInput and DataOutput.
