Why Ranger Startup Fails During the Cluster Installation?

Problem

During cluster installation, Ranger fails to be started, and the error message "ERROR: cannot drop sequence X_POLICY_REF_ACCESS_TYPE_SEQ " is displayed in the task list of the Manager process. How do I resolve this problem and properly install Ranger?

Answer

This issue may occur when two RangerAmdin instances are installed. If the instance installation fails, manually restart one RangerAdmin instance and then restart the other instance.
