Apache Hadoop integration

WebHDFS access with mTLS

For loading and exporting data, Vertica can access HDFS clusters protected by mTLS through the swebhdfs scheme. You must create a certificate and key and set the WebhdfsClientCertConf configuration parameter. The parameter value is a JSON string listing name services or authorities and their corresponding keys, so you can configure access to more than one HDFS cluster.

You can use CREATE KEY and CREATE CERTIFICATE to create temporary, session-scoped values. These keys and certificates are stored in memory, not on disk. You can set the configuration parameter at the session or database level.

For details and examples, see HDFS file system.
