This was the problem. Here a possible work around:
public static class MyBytes extends BytesWritable {
public MyBytes() {
super();
}
public MyBytes(byte[] data) {
super(data);
}
/**
* Set the size.
* @param size The new size.
*/
@Override
public void setSize(int size) {
boolean resize = size > getCapacity();
super.setSize(size);
if (resize) {
setCapacity(size);
}
}
}
