If the DEBUG level is enabled, the sensitive information will be exposed via the requests and responses output log. The entire lists of impacted requests and responses are:
AlterConfigsRequest
AlterUserScramCredentialsRequest
ExpireDelegationTokenRequest
IncrementalAlterConfigsRequest
RenewDelegationTokenRequest
