> Project: Hadoop Common
> Issue Type: Sub-task
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Labels: pull-request-available
>
> ContainerLogAppender and ContainerRollingLogAppender both have quite similar
> functionality as RollingFileAppender. Maintenance of custom appenders for
> Log4J2 is costly when there is very minor difference in comparison with
> built-in appender provided by Log4J.
> The goal of this sub-task is to replace both ContainerLogAppender and
> ContainerRollingLogAppender custom appenders with RollingFileAppender without
> changing any system properties already being used to determine file name,
> file size, backup index, pattern layout properties etc.
