Description

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.
