[chef] Re: Overriding node attributes with a wrapper cookbook

[Torben Knerr < >]

Hi Jay,

try using `node.set['attr_name'] = 'value'` in your wrapper *recipe* before you `include_recipe 'hadoop'`.

If the node attribute you are trying to set from the wrapper cookbook is used for computing other attributes in the hadoop cookbook you have to reload the hadoop attributes [0]

E.g. in `my_wrapper::default` recipe:

```

node.set['hadoop']['foo'] = 'bar'

node.from_file(run_context.resolve_attribute("hadoop", "default.rb"))

include_recipe 'hadoop::default'

```

HTH,

Torben

I'm hoping someone can help me figure this one out.

my_wrapper_cookbook depends on the community hadoop cookbook.  Each recipe in the hadoop cookbook has an 'include_recipe hadoop::repo' in order to set up the appropriate yum/apt repos for installation.

I want to use local repo mirrors to speed up the installation process because I'm installing hadoop clusters via automation to run testing every night.  The installation process takes a long time.  

I'm trying my_cookbook -> attributes -> repos.rb and setting node.override there.  These do not seem to be picked up when I converge the node.  Instead, the attributes are being set via hadoop::repo for every recipe that is run since each recipe in the hadoop cookbook includes the repo recipe.
