Package org.apache.hadoop.hdfs.util

Class AsyncRFAAppender

java.lang.Object

org.apache.log4j.AppenderSkeleton

org.apache.log4j.AsyncAppender

org.apache.hadoop.hdfs.util.AsyncRFAAppender

All Implemented Interfaces:

org.apache.log4j.Appender, org.apache.log4j.spi.AppenderAttachable, org.apache.log4j.spi.OptionHandler

public class AsyncRFAAppender
extends org.apache.log4j.AsyncAppender

Until we migrate to log4j2, use this appender for namenode audit logger as well as datanode and namenode metric loggers with log4j properties, if async logging is required with RFA. This appender will take parameters necessary to supply RollingFileAppender to AsyncAppender. While migrating to log4j2, we can directly wrap RFA appender to Async appender as part of log4j2 properties. However, same is not possible with log4j1 properties.
