             Summary: Add distributed tracing integration to YARN
                 Key: COMDEV-183
                 URL: https://issues.apache.org/jira/browse/COMDEV-183
             Project: Community Development
          Issue Type: New Feature
            Reporter: Colin Patrick McCabe


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.
