---------------------------------------------------------

Also the code snippet in section I.2 is not correct. I am assuming that the APIs got changed
after the write-up in the book. Here is a sample code which compiles currently
{code}
		Configuration conf = HBaseConfiguration.create();
		SpanReceiverHost spanReceiverHost = SpanReceiverHost.getInstance(conf);
		TraceScope getSpan = Trace.startSpan("Gets", Sampler.ALWAYS);
		try{
			System.out.println("Is tracing on :"+Trace.isTracing());
			HTable table = new HTable(conf, "t1"); 
			Get get = new Get(Bytes.toBytes("r1"));
			Result res = table.get(get);
			System.out.println(res.toString());
			table.close();
		} catch(Exception e) {
			getSpan.close();
		} finally {
			getSpan.close();
		}
{code}
