Allen Wittenauer commented on YETUS-561:
----------------------------------------
After playing around, JDK8u131/9's default of using the docker memory limit is
actually problematic. I fired up a docker container with -m 100m and just
watched everything come to a screaming halt, when it would have been much
better to just kill it off. We might save people a lot of heartache if we do a
lower bounds check.
Also, [~mdrob], you make a good point and maybe we should set a default. As
you said, 4g is probably a reasonable default unless others have a different
opinion.

> Hadoop is blowing up nodes due to unit tests that consume all of RAM. In an
> attempt to keep nodes alive, Yetus needs the ability to put an upper limit on
