Jason Lowe commented on MAPREDUCE-6768:
---------------------------------------
Thanks for the patch!
I suspect this patch is going to be appropriate for more than just trunk, so as
such it'd be good to avoid the lambda use.
I think only a 800 msec wait is going to be too short if the test runs on a
slow VM or some other hiccup occurs.
Nit: Any reason to wait 100mec instead of 10 per iteration? Yes, I'm overly
sensitive to sleeps lately with all the slow YARN tests. ;-)
