Hi, in our test environment I try to test the upgrade from cdh4.2.0 to cdh5.1.2 with replication.
before the upgrade I copied the whole hbase cdh4 folder to from the master to the slave cluster and configured replication. This was working. After the upgrade I could not get the replication running again. The Problem seems to be that the hbase.id is the same on both cluster. The regionserver tells me: INFO org.apache.hadoop.hbase.replication.regionserver.ReplicationSource: Closing source 1 because: ClusterId xyz is replicating to itself: peerClusterId xyz I changed the hbase.id manual, but that does not work because the hbase master does not start. How can i change the hbase.id or create a new one? We run 2.3.0-cdh5.1.2 in our environment. Regards Hansi
