Experience running MRv1 jobs against YARN clusters

Hello.

I am trying to find our about the experience MapReduce users have with
real-life experience running MRv1 (old-API) applications against YARN cluster.

What's good/bad?

How big is the hassle of making these applications to run on YARN?

Any cases where one had to make modifications in the application code to make
the transition?

I'd be really grateful for the feedback. Please don't hesitate to send it to
me privately if you don't want to share it on the list.

Appreciate,
  Cos
