Hi @rahuledavalath  We can use the HBase replication process for the data copy between the two CDP clusters, like production to DR. We have multiple open documents for the setting Hbase replication please follow the docs for setting the replication between two cluster to synchronise the data. https://docs.cloudera.com/cdp-private-cloud-base/7.1.6/hbase-backup-dr/topics/hbase-replication.html https://blog.cloudera.com/apache-hbase-replication-overview/     ...

@rahuledavalath In a 3-node ZK cluster, we can only afford to lose 1 instance/node at once. However, having this cluster across two geo-locations could put us in a difficult position. So, it will be a good idea to build the cluster across 3 regions, with one instance in each. ... View more

Hi @rahuledavalath ,   Generally, having internet access on the nodes where you are installing CDP Private Cloud simply saves you a few manual steps. However, it is absolutely acceptable to have nodes without internet and do an installation on "air-gapped" environment (e.g. see here: https://docs.cloudera.com/cdp-private-cloud-experiences/1.3.3/installation/topics/cdppvc-installation-airgap.html)   As for license activation, there is no need for internet access either. The license you get from Cloudera is a text file. As long as you upload it to Cloudera Manager in the appropriate installation step, there is no internet validation that needs to happen. Everything is self-contained on your hosts.     Hope this helps, Alex ... View more

Yes you can Are you telling internet is not required to activate the license while uploading the license to cloudera-manager  ? ... View more
