Daniel Templeton commented on YARN-8480:
----------------------------------------
I don't disagree that in terms of general use cases there's overlap between
boolean resources and node attributes. From the perspective of fair scheduler,
however, there's a big difference. Boolean resources are a simple mechanism
for a pure label resource that is a minor extension of existing capabilities.
Node labels or node attributes will be a major integration effort.
While much of this work touches the common code, what we're proposing here is
not intended as a general solution. Capacity scheduler is where the work for
node attributes is happening, and we don't propose to change that or muddy
those waters. This JIRA is intended only to provide a pure label resource for
fair scheduler that isn't as heavy.
