Chris Riccomini commented on MAPREDUCE-3068:
--------------------------------------------
Arun says in https://issues.apache.org/jira/browse/MAPREDUCE-3065 that the NM
should be modified to do this.
Based on poking around, it appears that bin/yarn-config.sh is a better place to
do this, as it then makes it into the RM, NM, and the Container from there
(given that the container launch context gets the env variables from its parent
process, the NM).
Does anyone have an argument for not doing it in yarn-config.sh? Already tested
locally, and it appears to work.
> Should set MALLOC_ARENA_MAX for all YARN daemons and AMs/Containers
