Steve Loughran commented on YARN-4169:
--------------------------------------
I'm not the person to review YARN patches, I'm afraid.
Looking at the tests briefly
# you can use Java 7 <> tags in constructors; the old code was for java 6 and
can be upgraded on the changed lines.
# no need to catch InterruptedExceptions and {{AssertFail()}}. Simply have the
test declare it throws {{InterruptedException}} and JUnit will do the rest.
