Jason Lowe commented on MAPREDUCE-6768:
---------------------------------------
bq. I guess I must be following some bad practice I have seen in the code base.
It's not a terrible practice, just that I've been sensitive to unnecessarily
long sleeps in unit tests lately. See the discussion at YARN-5393 for details.
+1 pending Jenkins. The patch still can't be used as-is on other branches
since JDK7 will want task1Attempt2 to be final for use in the inner class, but
that's something I can easily fix during the commit.
