Feng Yuan commented on YARN-6276:
---------------------------------
[~jlowe],GC maybe one kind of reason, by my guess.
My idea is "There is some reason can lead to sub process didnt respones the
kill -9 signal from superstratum process."
Because in some node,there is orphan YarnChild process(mr).
> Now container kill mechanism may lead process leak
