Jeff Buell commented on YARN-938:
---------------------------------
Yes, I spent a lot of time putting together high-performance hardware and
tuning the software stack. While "out of the box" tests have their place, it
is much easier to analyze performance differences when both configurations are
pushed to their limits. Tunes not only improve elapsed time, but almost always
they improve test repeatability and execution uniformity across the cluster.
The latter allows performance data to be collected on one machine with
confidence that it represents all machines in the cluster.
