Mayank Bansal commented on YARN-919:
------------------------------------
Thanks [~hitesh] for comments
The primary intention for this JIRA is to provide some handy way for users to
set the parameters.
I think you are right bin/yarn already set the defaults which I can remove from
this patch , however We need something like this in yarn-env.sh may be
commented for now by that user doesnt have to dig around the documentation to
increase the sizes for memory.
thoughts?
Thanks,
Mayank

> Right now there are no defaults in yarn env scripts for resource manager nad
> node manager and if user wants to override that, then user has to go to
> documentation and find the variables and change the script.
> There is no straight forward way to change it in script. Just updating the
> variables with defaults.
