Description

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.

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