5. Check YOUR_MASTER_COMPONENT? for deployment and ambari server node ________________________________ From: Dmitry Sen <[email protected]> Sent: Thursday, November 12, 2015 9:54 AM To: [email protected] Subject: Re: Ambari commandScript running on ambari server itself
Hi, You can 1. Define a new master component for your service in metainfo.xml 2. Create for your stack role_command_order.json like stacks/HDP/2.3/role_command_order.json? , add here dependency "YOUR_OTHER_COMPONENTS-START" : ["YOUR_MASTER_COMPONENT-START"], or "YOUR_OTHER_COMPONENTS-INSTALL" : ["YOUR_MASTER_COMPONENT-START"],? 3. Implement certificates generation logic at YOUR_SERVICE/1.0/scripts/master_component.py . The certificates should be located under /var/lib/ambari-server/resources/ , it's a shared directory by ambari server:8080 4. Install ambari agent on the Ambari Server node BR, Dmytro Sen ________________________________ From: Henning Kropp <[email protected]> Sent: Wednesday, November 11, 2015 11:21 PM To: [email protected] Subject: Re: Ambari commandScript running on ambari server itself Hi, maybe /var/lib/ambari-server/resources/custom_action_definitions/system_action_definitions.xml and /var/lib/ambari-server/resources/custom_actions/scripts could work for your purposes?

And I have a specific requirement - run some code locally on Ambari server right after deployment process starts but before any service components are installed on chosen hosts. This "local" code is supposed to do 2 operations: 1) generate some files (e.g. certificates/tokens) 2) that are to be copied/distributed to all master hosts. Something similar can be found in Ansible and it's named "local-action". Is there any recommended way to declare such local command script that runs on Ambari Server itself ? I mean, of course, I have 2 options for desired automation, but they all "suck", I think: - I can code it in Ansible or bash and run prior to cluster deployment - I can code it in inside master commandScript's install function with Execute("generate.sh > generate.out && scp generate.out user@master-host-1:/home/user/"). But it'd be much better if Ambari had such functionality and I could have done all operations from just a single Ambari Web Ui. Any suggestions ?
