             Summary: Timeline server span receiver for htrace traces
                 Key: YARN-2903
                 URL: https://issues.apache.org/jira/browse/YARN-2903
             Project: Hadoop YARN
          Issue Type: Task
            Reporter: Billie Rinaldi
            Assignee: Billie Rinaldi


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.
