------------------------------------
Summary: Add health check endpoint to Kudu webserver
Key: KUDU-3308
URL: https://issues.apache.org/jira/browse/KUDU-3308
Project: Kudu
Issue Type: Improvement
Components: server
Reporter: Bankim Bhavsar
For integrating with Kubernetes, it'd be good to add a webserver endpoint
(/healthz) that exposes health of the kudu cluster.
We need something that's very lightweight that responds back quickly with
simply HTTP status code. This endpoint is expected to be queried 5-10 secs. If
required, we can add a query parameter that'll return back more detailed
information.
The idea is to use this with livenessProbe/readinessProbe/startupProbe in
Kubernetes.

As a workaround, currently we can use the base landing page /.
