             Summary: agent.ini should be supported by default
                 Key: SLIDER-166
                 URL: https://issues.apache.org/jira/browse/SLIDER-166
             Project: Slider
          Issue Type: Bug
          Components: agent-provider
    Affects Versions: Slider 0.40
            Reporter: Sumit Mohanty
            Assignee: Sumit Mohanty
             Fix For: Slider 0.40


Currently, agent.ini file is explicitly provided by the users when creating application instance. The agent.ini file should be created per application instance as its possible for slider-agent instances for specific application instance to have unique configurations.

For example, a user may want to debug agents at the level DEBUG for a specific application instances while not requiring other applications to also run with DEBUG level for agent logs.

Proposal:
* Slider will have a default agent.ini that gets automatically uploaded
* Have folks provide overrides when creating an app
* AM patches the default using overrides and then drops the .ini somewhere in the app instance specific directory (default could be in a well-known place)
* The patched .ini is then handed off to all agent instances through YARN localized file support
