Description

As part of the web UI we can show application and container history.

The current pages are mocked up and do not show the real history. Before the changes can be made on the web UI side we need to provide the history via a REST interface so it can be consumed by the UI.

All web service code is located in package https://github.com/apache/incubator-yunikorn-core/tree/master/pkg/webservice. When running the scheduler locally (from K8shim using "make run"), the REST APIs can be accessed via

• http://localhost:9080/ws/v1/apps
• http://localhost:9080/ws/v1/queues
• http://localhost:9080/ws/v1/nodes

We need to add another endpoint to provide data to yunikorn-web to render the app/container history page. Please check with akhilpb for the desired data format, etc. That issue is tracked via YUNIKORN-8.
