Anoop Sam John commented on HBASE-26193:
----------------------------------------
Keeping the WAL directory and making sure that is available under the new HBase
cluster can solve the issue. Even if we keep the meta location only in zk (as
per now) or keep in master region + zk.
+1 to this idea keeping meta location in master region.
> Do not store meta region location as permanent state on zookeeper

> Key: HBASE-26193
> URL: https://issues.apache.org/jira/browse/HBASE-26193
> Project: HBase
> Issue Type: Improvement
> Components: meta, Zookeeper
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
>
> As it breaks one of our design rules
> https://hbase.apache.org/book.html#design.invariants.zk.data
> We used to think hbase should be recovered automatically when all the data on
> zk (except the replication data) are cleared, but obviously, if you clear the
> meta region location, the cluster will be in trouble, and need to use
> operation tools to recover the cluster.
> So here, along with the ConnectionRegistry improvements, we should also
> consider move the meta region location off zookeeper.
