Roman Shaposhnik commented on BIGTOP-275:
-----------------------------------------
Cos, this is the first time I see $var use in templates. What does it mean
exactly? My reading of Puppet docs
(http://docs.puppetlabs.com/guides/templating.html#referencing-variables)
reveals the following ways of reference a var inside of an erb template:
# Ruby instance variables — that is, @fqdn, @memoryfree, @operatingsystem,
etc.
# Ruby local variables — that is, fqdn, memoryfree, operatingsystem, etc.,
without the prepended @ sign.
Is there any reason we should be using $var ?
> scoping of variable in puppet code is incorrect

> It seems that the variable that are referenced in our templates are actually
> coming from cluster.pp scope and not individual modules. This is especially
> visible in hadoop module. Need to investigate.
