Arun C Murthy commented on MAPREDUCE-3068:
------------------------------------------
No, not another *-env.sh file.
It's simpler to make it configurable via yarn-site.xml.
Add a yarn.nodemanager.admin-env config which takes 'key=value','key=value' etc.
There is similar functionality for MR applications - take a look at
MRJobConfig.MAPRED_ADMIN_USER_ENV and how it's used in MapReduceChildJVM.setEnv
which uses MRApps.setEnvFromInputString. Maybe you can move
MRApps.setEnvFromInputString to yarn-common and use it.
> Should set MALLOC_ARENA_MAX for all YARN daemons and AMs/Containers
