Problem setting up replication on 0.94.1
Hi,

I'm having problems setting up replication on HBase 0.94.1. I have
installed HBase on two clusters (the slave is using a pseudo-distributed
installation), and the ids are:

[zk: hbdndl3:2181(CONNECTED) 0] get /hbase/hbaseid
18704@hbnndl1f3853040-98e1-4236-99bf-662196b5aaf4

[zk: hbase-backup:2181(CONNECTED) 3] get /hbase/hbaseid
�9782@hbase-backup55da74bc-47b7-4daf-af65-c37ebb762a3e

As you can see in the second line of the following log, the master is
getting the peer id connecting to the master zookeeper ensemble:

2012-10-04 16:44:18,837 DEBUG org.apache.hadoop.hbase.zookeeper.ZKUtil:

f3853040-98e1-4236-99bf-662196b5aaf4

Of course the id it gets is the same as the master id and nothing gets
replicated.

Have you any idea of what could be wrong?

Thanks.
