Hi, I just moved tez-swimlanes from my github into master (TEZ-1332).
This is written in python at the moment and works off the tez logs to make diagrams which look like.
http://people.apache.org/~gopalv/query27.svgThis isn't the final version of the visualization, so I'd like some feedback on making it useful, like what needs documenting or explaining in there.
Cheers, Gopal
