Grant Henke commented on KUDU-2418:
-----------------------------------

Was this done in 1.8.0? I suspect a bad fix version. Will remove it. Feel free to correct it though.

> There's an established Kudu workflow for manually "repairing" a tablet that has only one working replica, using the unsafe_config_change CLI tool. I used quotes around repairing because while it brings the tablet back to a healthy state as far as Kudu is concerned, the tablet may have suffered data loss. In some circumstances, however, that's something users are willing to accept.
> The problem is when this happens writ large, to an entire cluster. For example, suppose a three node cluster hosting 1000 tablets loses two nodes. It should be possible to automate this repair process so that users needn't script it themselves.
