Andy,
"YARN" is NOT "MRv2". That seems to be a major confusion with people
thanks to everyone mixing up the terms. See this small post for a
clear difference:

They are not comparable.
YARN also known as MRv2 is the newer version of MapReduce also known as MRv1.

Subject: Differences between YARN and Hadoop
To all,
I have a few questions regarding YARN (with respect to Hadoop):
Are YARN and Hadoop separate, or is YARN the successor to Hadoop?
What are the major conceptual differences between YARN and Hadoop?
I have further questions, but they may or may not make sense depending on the
answers to the above.
Thanks in advance!
Tom Brown
