[jira] [Created] (KUDU-3308) Add health check endpoint to Kudu webserver

Bankim Bhavsar created KUDU-3308:
------------------------------------

             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 /.
