My real issue is that in writing my own RecordReader, I am trying to

set(byte[], int, int) adds buffered capacity of the magnitude 3/2 *
size.
In any case, with BytesWritable, you need to assume that the backing
array is longer than the data. You always need to do:
bw.getBytes(), 0, bw.getLength()
to get the bytes and the valid range of data. Almost all contexts in
Java allow you to specify byte[], offset, length...
