How to implement BDR with kerberos and tls enabled cluster

pdev — Fri, 16 Sep 2022 14:38:26 GMT

Hi,

I am running cdh 5.14.0 cluster version both on Prod and DR cluster. Both cluster are Kerberos and TLS enabled with the same kdc server.

Could anyone guide me on how to do BDR between Kerberos enabled clusters. As I was not able to find any proper guide on the Cloudera website.

Please help me or provide any docs related to this.

Appreciate your help.

Thanks

Please refer document [1] for details on how to enable replication between cluster with kerberos configuration.

To configure encryption of data transmission between source and destination clusters:

Enable TLS/SSL for HDFS clients on both the source and the destination clusters. You may also need to configure trust between the SSL certificates on the source and destination. The certificates of the source cluster should be trusted by your destination cluster.
Enable TLS/SSL for the two peer Cloudera Manager Servers.

Refer link [2] for more details.

Thanks, Paras

will try and let you know. One more question, do BDR works between two different CDH versions?

like 5.14 and 5.16 ?
