BDR Replication between secure and non secure cluster

avatar
Explorer

Hello,

 

I am not sure if this is the right board to post this question.

 

I have two clusters and one of them is secured with Kerberos.

 

The requirement is to configure replication between these two cluster using BDR.

 

Source : Unsecure cluster

Targent: Secure Cluster

 

Is it possible to set this up successfully?

 

Thanks in advance

Sorry to Resurrect this from 2 years ago, but does this have to do with the credential being used or the fact that kerberos is enabled at all?

 

 

Example, if I had a non-kerberized superuser on the source(kerberized) cluster, could I then use BDR to replicate the data?  The situation I am in is such that even if I did have kerberos available to me, my destination would not be in the same realm, so if possible I would prefer to bypass kerberos as its less important that the destination be kerberized (It's isolated by firewall rules at a perimeter), I just want the cluster's data mirrored.

Hi @MikeJones,

 

I'm not sure what you are saying.  Either you have Kerberos authentication enabled in a cluster or you don't.  In order to use BDR HDFS replication, you need to have Kerberos enabled on both clusters or not enabled in both clusters.

 

For information about how BDR replication supports replicating between clusters in different realms, see:
