But there are many more mapreduce.* properties. ...
Does anyone have more information on those with respect to whether they
are relevant to YARN, and if so, what they exactly mean in the YARN context?
I am trying to optimize settings in order to use as much RAM and CPU as
possible. The cluster has 8 node managers each with 96GB RAM and 16 CPUs
(cpuinfo: Intel(R) Xeon(R) CPU E5620 @ 2.40GHz)

In CM, there are a number of options for setting mapreduce.*
configuration properties on the YARN client page.
Some of the properties and their explanations in the GUI still refer
to JobTracker and TaskTracker, e.g.,
I wonder whether these and a number of other mapreduce.* (e.g.,
mapreduce.job.reduces) properties are observed by the MR2
ApplicationMaster (and how), or not.
Can anyone clarify or point to respective documentation?
