             Summary: Get rid of using macros as enviroment variables for nagios
                 Key: AMBARI-6286
                 URL: https://issues.apache.org/jira/browse/AMBARI-6286
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.7.0



    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.
