HBASE-30167: Document the Read Replica feature#8459
Conversation
| ### Custom `hbase:meta` per cluster | ||
|
|
||
| Every cluster sharing a `hbase.rootdir` needs its own `hbase:meta`, because region assignments are | ||
| node-scoped and cannot be shared. Other system tables (`hbase:namespace`, `hbase:acl`, `hbase:replication`) |

hbase:namespace has been deprecated since 3.0.0 and will be removed in 4.0.0. https://github.com/apache/hbase/blob/master/hbase-common/src/main/java/org/apache/hadoop/hbase/TableName.java#L110-L118
We don't need to mention it here for master branch.
