java.lang.ClassNotFoundEception: com.cloudera.navigator.audit.hdfs.HdfsAuditLoggerCdh5 error during hdfs namenode cdp 7 to cdh 6 rollback

Explorer

Hi all,

 

I am getting the below error when I perform hdfs namenode rollback during CDH 6 rollback from CDP 7;

 

sudo -u hdfs hdfs --config /etc/hadoop/conf.rollback.namenode/ namenode -rollback

 

 

I am following the rollback steps from this documentation, the step that I performed is Step 9->3f;

https://docs.cloudera.com/cdp-private-cloud-upgrade/latest/upgrade-cdh6/topics/install_rollback-cdh6...
