    Description

      Servers that are participating in the LogService's quorum will die unexpectedly.

      While RAFT/Ratis would be capable of recovering from this scenario, we likely do not want to do this because of the associated cost of shipping the edits for a LogStream to a new peer.

      Instead, the simple solution would be for a RegionServer to create a new LogStream. This is analogous to us rolling an (hdfs file-backed) WAL when we have errors writing/syncing it.
