I'm not sure if a documentation exists, but here's the procedure on how to add a custom action.
To define a host level custom action for a service component, you would have to do the following: - Add the custom action for the service component to metainfo.xml https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/common-services/HDFS/2.1.0.2.0/metainfo.xml#L39-#L46 - Add the definition of the custom action in the component's script https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/common-services/HDFS/2.1.0.2.0/package/scripts/namenode.py#L120-#L124 Please note that the naming convention for the action in metainfo.xml is *MY_CUSTOM_COMMAND* and the corresponding function signature in the script would be *my_custom_command (self, env)* On Mon, Feb 22, 2016 at 6:27 AM, Zhang Ruiqiang <[email protected]> wrote: > Hi all: > I want to add a host level action, is there any document that I can > follow? > > Thanks! > > > > -- *Mithun Mathew* (Matt) - www.linkedin.com/in/mithunmatt/
