Haibo Chen commented on YARN-4061:
----------------------------------
[~jrottinghuis] do you think we should at least target this at hadoop 3.0 GA? I
think most users would expect hadoop GA version, i.e. ATSv2 to not easily lose
data when backend is down for a while, even though it is not super critical to
run YARN applications .
