Karthik Kambatla commented on YARN-2965:
----------------------------------------
I am assuming there will be a config to turn on/off resource-tracking; for now,
we need not expose this config to the end-user. In addition to this config, I
think it might make sense to add a config to turn reporting to the RM on/off;
people might just want to log this information through metrics.
Slightly orthogonal - we were thinking of tracking the resource usage per
container as well. Do you think this work can be extended to collect but not
report that information as well?
