    I tried to remove HBaseResult and HBaseKey using directly Tuple2<ImmutableBytesWritable,
Result> as you suggested but this does not work because of Avro serialization..at the moment
I was trying to use the following:
    	public Tuple2<ImmutableBytesWritable, Result> nextRecord(
    			Tuple2<ImmutableBytesWritable, Result> reuse) throws IOException {
    		if (this.tableRecordReader == null)
    			throw new IOException("No table record reader provided!");
    		try {
    			if (this.tableRecordReader.nextKeyValue())
    				Result currentValue = tableRecordReader.getCurrentValue();
    				currentValue.setExists(Boolean.TRUE);//fix null pointer in avro serialization
    				ImmutableBytesWritable currentKey = tableRecordReader.getCurrentKey();
    				reuse.setField(currentKey, 0);
    				reuse.setField(currentValue, 1);
    				return reuse;
    			} else
    				this.endReached = true;
    		} catch (InterruptedException e) {
    			LOG.error("Table reader has been interrupted", e);
    			throw new IOException(e);
    		return null;
    How do I have to proceed?
