> Project: Ratis
> Issue Type: Bug
> Components: server
> Reporter: Mukul Kumar Singh

> This bug was simulated using Ozone using Ratis for Data pipeline.
> In this test, one of the nodes was shut down permanently. This can result
> into a situation where a candidate node is never able to move out of Leader
> Election phase.
