Subject Visualize DAG of a pipeline
Date Tue, 05 Feb 2013 03:13:28 GMT
Hi crunch users,

I would like to know if there are any tool to help me understand crunch
optimized MR stages.

Particularly, I think I need to see the DAG of job stages. I'm writing a
pipeline consists of several joins. The pipeline produces significant
more intermediate output than I expect. I want to investigate what's going
wrong there.
