Work Description: rohdesamuel commented on issue #8012: [BEAM-6777] Add
HealthDaemon and tests
URL: https://github.com/apache/beam/pull/8012#issuecomment-472110777
> Is the expectation that this will ping an endpoint hosted by dataflow
service or the runner harness?
Neither, this will ping the existing Healthchecker sibling container that
already sends health checks to Dataflow. The Healthchecker container will then
communicate the health to the Dataflow service.

> If the Python SDK Harness crashes in any way (user code exception, OOM, etc)
> the job will hang and waste resources. The fix is to add a daemon in the SDK
> Harness and Runner Harness to communicate with Dataflow to restart the VM
> when stuckness is detected.
