> Distributed tracing allows users to follow a request through the entire distributed system, crossing network and project boundaries.  The Apache HTrace project has added distributed tracing to HDFS and HBase (among other projects).  We should add tracing to YARN so that MapReduce, spark, and other frameworks can make use of it.
> Tracing should identify which yarn rpcs were made, and also tag top level trace spans with the yarn job that they are associated with.
