> Can commons-logging.properties be pulled from hadoop-core?
> ----------------------------------------------------------
>
> Key: HADOOP-3368
> URL: https://issues.apache.org/jira/browse/HADOOP-3368
> Project: Hadoop Core
> Issue Type: Improvement
> Affects Versions: 0.19.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Attachments: hadoop-3368.patch
>
>
> In the root of hadoop-core.jar is a log4j.properties and a
> commons-logging.properties
> while this provides good standalone functionality to hadoop, it complicates
> anyone else trying to control the logging, and use the libraries in-process.
> In particular, there is a commons-logging.properties file that selects Log4J
> as the back end. This is not needed as
> -log4j is automatically picked up if it is on the classpath
> -if it is not on the classpath, asking for it is generally considered bad
> form
> If you look at the commons-logging configuration details:
> http://commons.apache.org/logging/guide.html#Configuration
> you will see that that such a properties file takes priority over any setting
> through system properties, which makes it very hard to override the settings
> without adding multiple commons-logging.properties files and playing with
> their priority settings
> If you pull the commons-logging.properties file from hadoop-core log4j will
> still be picked up by default, but it becomes easier for people to turn on
> different logging infrastructures if they want to. It should have no visible
> impact on the end user experience (unlike pulling log4j.properties)
