Is it possible？ Replication from insecure HBase cluster to a secure HBase cluster(using Kerberos)

Hello all,

       

          Recentlly I met a problem about HBase replication configuration. Is it possible to replicate data from a normal HBase(authentication = simple) to a secure HBase (authentication = kerberos).   ?

 

          I`m using HBase (hbase-0.94.2-cdh4.2.0) on Hadoop (hadoop-2.0.0-cdh4.2.0). I have two HBase cluster--A, B, they are on different Hadoop cluster, using different namenode and zookeeper.quorum. 

 

         Now, the Cluster A is a insecure Cluster ,which means the hbase.security.authentication is simple. But Cluster B is a secure HBase, it is using kerberos for hbase.security.authentication. 

 

        Now my problem is, I hope A can replicate its table to B, using HBase Replication. Is is possible to make it ?

 

       By the way, I saw the "Configuring Secure HBase Replication" guide page in cloudera website, but I found that guide is talking about  "two realms". Now I have only one HBase cluster with Kerberos, the other one is an insecure HBase with simple authentification. I want to make a master-slave replication with the insecure HBase as the master, and the secure HBase as slave. How can I do that?

Errr… maybe… 

Headless keytab on the insecure cluster nodes and use the same LDAP server for authentication?
