Description

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
