Sunil Govindan commented on YARN-5592:
--------------------------------------
Even if we limit to add op alone, as [~leftnoteasy] told there will be impact
for scheduler. We assume all resource obj has same resource info.
I think lets take a pause on this for now. Because any change in resource
comparision logic in DominantRC or Resources class will have huge impact on CS
container allocation performance. Thanks [~leftnoteasy] for pointing it out.
[[email protected]] thoughts? we can live by restarting RM for now i think.
But sudden change ll affect a lot of perf.
