@jojochuang It just provide options to modify log4j configuration when we enable hdfs audit async logger. In most scenarios, those configurations are irrelevant. But in high concurrency scenarios, namenode will generate a lot of audit logs, and a large amount of audit log output will affect the performance of namenode. So in our production env, namenode generates 50w+ per min audit logs, we set AsyncAppender Blocking (default value true) to false and buffersize (default value 128) to 1024 to ensure namenode performance ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
