Arun C Murthy commented on MAPREDUCE-3068:
------------------------------------------
Chris, setting this in yarn-default.sh will work for RM/NM itself.
However, the containers don't inherit NM's environment - thus we'll need to
explicitly do it. Take a look at ContainerLaunch.sanitizeEnv.
To be more general we need to add a notion of 'admin env' so admins can set
MALLOC_ARENA_MAX and others automatically for all containers.
Makes sense?
> Should set MALLOC_ARENA_MAX for all YARN daemons and AMs/Containers
