Karthik Kambatla commented on YARN-1856:
----------------------------------------
As discussed on YARN-3, using cgroups for memory isolation/enforcement can be
problematic as it enforces an upper-bound on the amount of memory tasks can
consume and hence doesn't tolerate any momentary spikes.
Using it for monitoring, however, would help address YARN-1747.
I haven't yet looked at the cgroups-related source closely enough. Can post an
update once I do that.
