Subject [jira] [Updated] (MAPREDUCE-3248) Log4j logs from unit tests are lost
Date Mon, 24 Oct 2011 13:53:32 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3248?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Vinod Kumar Vavilapalli updated MAPREDUCE-3248:

    Attachment: MAPREDUCE-3248-20111024.txt

It is caused by both MAPREDUCE-3199 and MAPREDUCE-3003. Once the parent artifact for all the
modules got changed to hadoop-project via MAPREDUCE-3003, most of the mapreduce/yarn modules
lost hold of the log4j configuration. MAPREDUCE-3199 worsened it for every module.

The attached patch should work.

The alternative is to set the hard-coded location of log4j.properties in each module, which
won't be maintainable. Even relative links like maven.project.parent.* also break over time
as was found after MAPREDUCE-3003.
