Zhijie Shen commented on MAPREDUCE-6052:
----------------------------------------
Have a quick offline chat shortly with Junping. As there already exist code
duplication between copying regular files and tar ball files, let's just leave
the patch as what it is not to move fast for 2.6. Will file a separate
code-refactoring Jira to consolidate copying of regular files(jars)/log4j
file/tar balls.
Will go ahead to commit the current patch.
> Support overriding log4j.properties per job

> 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.
> {code}
> public static void addLog4jSystemProperties(
> String logLevel, long logSize, int numBackups, List<String> vargs) {
> vargs.add("-Dlog4j.configuration=container-log4j.properties");
> {code}
