> In our production environment, we occasionally encounter a problem where a 
> user submits an abnormal computation task, causing a sudden flood of 
> requests, which causes the queueTime and processingTime of the Namenode to 
> rise very high, causing a large backlog of tasks.
> We usually locate and kill specific Spark, Flink, or MapReduce tasks based on 
> metrics and audit logs. Currently, IP and UGI are recorded in audit logs, but 
> there is no port information, so it is difficult to locate specific processes 
> sometimes. Therefore, I propose that we add the port information to the audit 
> log, so that we can easily track the upstream process.
> Currently, some projects contain port information in audit logs, such as 
> Hbase and Alluxio. I think it is also necessary to add port information for 
> HDFS audit logs.
