HBase replication between TLS-enabled Cloudera Operational Database clusters fails due to hostname verification
7.3.2.10000
When you set up reverse HBase replication between two TLS-enabled Cloudera Operational Database clusters, replication fails if reverse DNS resolution is not configured between the clusters. During mutual TLS (mTLS) authentication, the source cluster sends its certificate, which contains the hostname. The target cluster validates the certificate against its truststore and then verifies that the client connection IP address matches the hostname in the certificate. Because reverse DNS resolution does not work between separate Cloudera Operational Database clusters by default, this verification check fails and the connection is rejected.
This issue occurs when all of the following conditions are true:
  • Both clusters have TLS enabled.
  • Hostname verification is enabled (hbase.client.netty.tls.verify.server.hostname and hbase.server.netty.tls.verify.client.hostname are set to true).
  • hbase.server.netty.tls.client.auth.mode is set to WANT or NEED.
  • TLS certificates are issued without an IP Subject Alternative Name (SAN).
  • Reverse DNS resolution is not configured between the clusters.
  • Mutual TLS trust is established between the clusters.

These are the default settings for a fresh installation of Cloudera Runtime 7.3.2.10000.

To bypass the client hostname verification check, add the hbase.server.netty.tls.verify.client.hostname = false property to the HBase Service Advanced Configuration Snippet (Safety Valve) for hbase-site.xml using Cloudera Manager.
