Overview (Ambari 1.5.0 or later)

Background

The Stack definitions can be found in the source tree at /ambari-server/src/main/resources/stacks. After you install the Ambari Server, the Stack definitions can be found at /var/lib/ambari-server/resources/stacks

The structure of a Stack definition is as follows:

|_ stacks
   |_ <stack_name>
      |_ <stack_version>
         metainfo.xml
         |_ hooks
         |_ repos
            repoinfo.xml
         |_ services
            |_ <service_name>
               metainfo.xml
               metrics.json
               |_ configuration
                  {configuration files}
               |_ package
                  {files, scripts, templates}
