Eli Reisman commented on GIRAPH-232:
------------------------------------

Wonderful! This will give us our first real glimpse at the motor running with the hood open.
The scalability bottlenecks and (to quote an upsetting politician of recent times) the "Unknown
unknowns" this tool will reveal will be immensely helpful. Thanks so much for this!

> Currently a lot of Giraph's operations are not transparent. As a Hadoop job, the Giraph
logging is at the mercy of Hadoop's logging system and can disappear when one encounters a
memory issue.
