[jira] [Created] (HBASE-20961) Recover RAFT quorum membership loss

Josh Elser created HBASE-20961:
----------------------------------

             Summary: Recover RAFT quorum membership loss
                 Key: HBASE-20961
                 URL: https://issues.apache.org/jira/browse/HBASE-20961
             Project: HBase
          Issue Type: Sub-task
            Reporter: Josh Elser


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.
