> HDFS is tracing using htrace now, as are other applications including HBase and Accumulo.
 It would be a nice feature if we enabled writing traces to the timeline server.  I envision
an htrace SpanReceiver implementation that uses the TimelineClient to store tracing data.
 The htrace API may end up being a more convenient way to instrument applications to store
timeline data in the timeline server.
