[DISCUSS] SLIDER-799 terminology: escalate vs relax
I'm documenting the SLIDER-799 changes and its property names.
This is our chance to get terminology right.
Should I call the action of going from a specific host to "anywhere" one of
[] Escalation
[] Relaxation
I've been using 'escalation', but think 'relaxation' may be better, we can have properties like 'yarn.placement.relax.time.seconds'
Which do people prefer?
Or does anyone have a better term?

Makes sense to me.

that's right.
'relax' defines the action —so explains what is happening.
Of course, 'escalate' defines why we are doing it -so would allow more flexibility in future for extra escalation policies (I can't think of any right now)

We are escalating the placement process because we cannot get the resource
we are looking for by means of relaxing the locality constraint.

In conjunction with placement, relax seems more appropriate.
Also, this feature is alluding to relaxing placement constraints.

I'm documenting the SLIDER-799 changes and its property names.
This is our chance to get terminology right.
Should I call the action of going from a specific host to "anywhere" one of
[] Escalation
[] Relaxation
I've been using 'escalation', but think 'relaxation' may be better, we can have properties like 'yarn.placement.relax.time.seconds'
Which do people prefer?
Or does anyone have a better term?
