为什么厨师属性被应用或忽略？

Question

我正在尝试设置 Chef 角色来安装 openjdk-7-jdk 和 tomcat7。我正在使用 java 和 tomcat 的 OpsCode 社区食谱。通过阅读文档，我相信我需要覆盖node[:java][:jdk_version] 和node[:tomcat][:base_version]。

我已经创建了following role JSON file：

name "tomcat7"
run_list "recipe[tomcat]"
default_attributes(
    :java => {
        :jdk_version => "7"
    },
    :tomcat => {
        :base_version => "7",
        :java_options => "-Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -Xms1536m -Xmx1536m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:+DisableExplicitGC"
    }
)

当我尝试使用 Vagrant 启动 VM 时，它会出现以下错误（请注意，它同时提到了 tomcat6 和 tomcat7）：

似乎node[:tomcat][:base_version] 属性被覆盖，因为它正在安装tomcat7 和tomcat7-admin。但是，它正在创建 tomcat6 目录。

完整的例子可以在https://github.com/McPolemic/tomcat_chef_example/找到。

在选择默认属性或我的属性时是否有押韵或理由？

我很确定这是配方中的错误 - 如果您覆盖 base_version，在某些情况下您还需要覆盖 config_dir。
