Subject [jira] [Commented] (MAPREDUCE-6768) TestRecovery.testSpeculative failed with NPE

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. ;-)
