>     Macros are normally made available to check, notification, event handler, etc. commands as environment variables. 
>     This can be a problem in a large Nagios installation, as it consumes some additional memory and (more importantly) more CPU. 
>     If your scripts don't need to access the macros as environment variables (e.g. you pass all necessary macros on the command line), you don't need this feature. 
>     You can prevent macros from being made available as environment variables by using the enable_environment_macros option.
>     
> we have 3 enviroment macros used in check_wrapper.sh, and some in other
> scripts, we can excplicetely set them to env by editting hadoop-commands.cfg
> Benefit: we can stop using expensive enable_environment_macros, and have
> alerts working on large cluster.
