Parameterize the WritableComparable there to eliminate warning.

<https://reviews.apache.org/r/1135/#comment3172>
Do we really need two booleans? It seems at a time data will be either in
byte[] or in timestamp, so one bool will suffice?

<https://reviews.apache.org/r/1135/#comment3174>
Arrays.fill() might be better here.

<https://reviews.apache.org/r/1135/#comment3173>
I think you want Arrays.equals() there.

<https://reviews.apache.org/r/1135/#comment3177>
System.arrayCopy() will be more efficient here.

System.arrayCopy() will be more efficient here.
