             Summary: Timeline server span receiver for htrace traces
                 Key: YARN-2903
             Project: Hadoop YARN

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.
