-------------------------------------------
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.
