---------------------------------------
yep, looked at this: it's there. Been used for a long time to set
{{MALLOC_ARENA_MAX}} on Linux
> allow setting env variables for components from json config

> Key: SLIDER-973
> URL: https://issues.apache.org/jira/browse/SLIDER-973
> Project: Slider
> Issue Type: Improvement
> Components: app-package, appspec
> Affects Versions: Slider 0.81
> Reporter: Sergey Shelukhin
>
> Sometimes, it is necessary to set an env variables for the component, e.g.
> HADOOP_JAAS_DEBUG is used in some cases to enable certain debug output.
> Is it possible to add the ability to set those in appConfig.json, the same
> way e.g. JVM args are set?
