If I have HBase replication set up, I can do this: > list_peers PEER ID CLUSTER KEY 1 zk1,zk2,zk3,zk4,zk5:2181:/hbase
Or I can do this: > list_peers PEER ID CLUSTER KEY 1 zk1:2181:/hbase 2 zk2:2181:/hbase 3 zk3:2181:/hbase 4 zk4:2181:/hbase 5 zk5:2181:/hbase Both appear to result in functional replication, but we have our suspicions that one or the other is incorrect in some subtle way we have not yet considered. Questions: 1. Is it valid to add the entire Zookeeper ensemble as the peers for replication? Or should we only be specifying one node? 2. If the latter, does that mean replication dies if the single ZK node dies? 3. If the former, which is the correct way to define the ensemble? The single-peer method, or multiple-peer method? -- *Tim Ellis: *Fifth Sigma, Inc. Multimedia and Technology++
