few days back we had a similar thread on checking nested attributes , chef has a helper to do it for knife plugins method https://github.com/opscode/chef/blob/master/lib/chef/knife/core/generic_presenter.rb#L177 , you can use the same logic before accessing or setting a nested atttribute

You are referencing a missing node['kafka'] hash, probably because you haven't included kafka as a dependency of this other cookbook.

Hi,

How do I prevent the below from happening?  I thought given the below logic it will always work.

I am trying to set  node['kafka']['brokerid'] only once.  How do I get NoMethodError?

44: 
 45>> if node['kafka']['brokerid'].nil?
 46:    node.set['kafka']['brokerid'] = Time.now.getutc.to_i
 47:  end
 48:  brokerid = node['kafka']['brokerid']
 49:   
 50:  template "/var/lib/kafka-0.7.2-incubating-src/config/server.properties" do
 51:    path "/var/lib/kafka-0.7.2-incubating-src/config/server.properties"
 52:    source "server.properties.erb"
 53:    owner "root"
 54:    group "root"
