Cannot find destination clusters for HBase replication policies
When you ping destination clusters using their host names, the source cluster hosts for HBase replication policies do not find the destination clusters. How to resolve this issue?
Cause
This might occur for on-premises clusters such as CDP Private Cloud Base clusters or CDH clusters because the source clusters are not on the same network as the destination Data Hub. Therefore, hostnames cannot be resolved by the DNS service on the source cluster.
Remedy
Add the destination Region Server and Zookeeper IP to host name
mappings in the /etc/hosts files of all the Region
Servers on the source cluster.
The following snippet shows the contents in a sample
/etc/hosts
file:
