> Add HTrace 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 P. McCabe
> Priority: Major
> Labels: Gsoc2016, gsoc, mentor
>
> 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. That would let
> us analyze information relevant to a particular YARN job or set of jobs.
> There are a lot of interesting projects here-- detecting hardware failures in
> production clusters, analyzing patterns in MR or Spark jobs, etc.
