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.
