---------------------------------------------------------
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}
