---------------------------------
Summary: Do not store meta region location 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
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.
