Hi!
I am developing my own custom app stack and bunch of services for Ambari
(not related to HDP).
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 ?
