Where is the Iteration and Loss output?

[fengbinchen]

I've tried mnist example on AWS and I didn't see any output like this:
I0215 04:45:41.444522 26306 solver.cpp:237] Iteration 0, loss = 2.45106
I0215 04:45:41.444772 26306 solver.cpp:253] Train net output #0: loss = 2.45106 (* 1 = 2.45106 loss)
......

Is this normal? Where can I find the Iteration vs Loss information? I can find the model and feature output in hdfs and the job finished without any exception.

You can open Spark web UI to check these

It should be in your executor log.
