ASF GitHub Bot logged work on HDFS-16266: ----------------------------------------- Author: ASF GitHub Bot Created on: 25/Oct/21 08:11 Start Date: 25/Oct/21 08:11 Worklog Time Spent: 10m Work Description: jojochuang commented on pull request #3538: URL: https://github.com/apache/hadoop/pull/3538#issuecomment-950643667 The API is declared Public, Evolving. If it stays in Hadoop 3.4.0 I am fine with it. We used to have an audit logger (Cloudera Navigator) that extends the AuditLogger interface. But we've moved away from that. Performance: It would have a slight performance penalty because every audit log op will always convert InetAddress to a string, regardless if audit logger is off (audit log level = debug or dfs.namenode.audit.log.debug.cmdlist has the excluded op)). It's probably acceptable since audit is logged outside of namenode lock. CallerContext: the caller context is probably a better option when you want to do fine-grained post-mortem anyway. Maybe we can modify the caller context to attach remote port so that it doesn't break api compatibility. Just a thought. -- This is an automated message from the Apache Git Service.

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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
