Today, I will talk to you about how to turn off the audit log function of Navigator. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

The audit function in the documentation purpose CDH allows the operation of the cluster to be recorded so that it can be queried during the audit. If Navigator is enabled, the audit log is aggregated into Navigator. However, when the Navigator service is stopped, the audit log will be dropped locally, taking up a lot of disk space. The following is mainly about how to turn off the audit log function.

1. To disable the audit log function of the cluster, you need to manually modify the configuration in each service, and then save the restart.

The system does not prompt to restart after the modification of 2.Impala. You need to restart it manually here. If you do not restart, Impala's audit collection function is still running and audit logs are still recorded in the audit directory.

3.HBase is selected for restart in this article, during which the HBase service will not be available. If you choose to scroll restart, it may take a very long time.

4. If you need to enable Navigator for audit later, you need to manually enable the audit collection feature for each service.
