Subject [jira] [Commented] (MAPREDUCE-6052) Support overriding log4j.properties per job
Date Thu, 09 Oct 2014 00:58:34 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6052?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14164497#comment-14164497

Vinod Kumar Vavilapalli commented on MAPREDUCE-6052:

bq. No matter which NM the containers will be launched, they will always get the same container-log4j.properties.
So, if we use customized log4j properties, do we need to distribute this file to all the NMs
(just like the default container-log4j.properties) ? 
Was asked to comment. This makes sense. Let's just make it a user-configuration of a local
log4j file that we accept and add it automatically to the distributed-cache.

> For current MR application, the "log4j.configuration" is hard coded to container-log4j.properties
within each node. We still need flexibility to override it per job like what we do in MRV1.

>     vargs.add("-Dlog4j.configuration=container-log4j.properties");
> {code}
