Subject Hadoop 2.7.2 Yarn Memory Utiliziation
Date Fri, 07 Oct 2016 19:31:48 GMT
I'm playing around with setting up a Hadoop 2.7.2 cluster with some configs
that I inherited and I'm running into an issue where YARN isn't utilizing
all of the memory available on the nodemanagers and seems to be limited to
2-3 map tasks for an application for some reason. Can anyone shed some
light on this or let me know what else I should look into?

Attached screenshots below of what I'm seeing.

Relevant configs that I'm aware of:
