Hadoop project use log4j 1.2.x, we can't config some properties of logger in log4j.properties file , For example, AsyncAppender BufferSize and Blocking see https://logging.apache.org/log4j/1.2/apidocs/index.html.

Namenode  should add some audit async logger log4j config In order to facilitate the adjustment of log4j usage and audit log output performance adjustment. 

The new configuration is as follows

dfs.namenode.audit.log.async.blocking false

dfs.namenode.audit.log.async.buffer.size 128
