Chris Douglas updated MAPREDUCE-1376:
-------------------------------------

    Attachment: M1376-0.patch

Patch:
* Adds a pluggable mechanism for resolving a user in the trace to another 
(defaults to Submitter, the current behavior)
* Fixes a minor bug in data generation that could write zero-length segments
* Includes resolver that consistently assigns users in the trace to a queue of 
target users

> Support for varied user submission in Gridmix

> Gridmix currently submits all synthetic jobs as the client user. It should be 
> possible to map users in the trace to a set of users appropriate for the
