Where do logs go in StandAlone mode

[Tim Smith]

Spark 1.0.0

I write logs out from my app using this object:

object LogService extends Logging {

/** Set reasonable logging levels for streaming if the user has not
configured log4j. */
 def setStreamingLogLevels() {
    val log4jInitialized = Logger.getRootLogger.getAllAppenders.hasMoreElements
    if (!log4jInitialized) {
      // We first log something to initialize Spark's default logging,
then we override the
      // logging level.
      logInfo("Setting log level to [WARN] for streaming example." +
        " To override add a custom log4j.properties to the classpath.")
      Logger.getRootLogger.setLevel(Level.WARN)
    }
  }
}

Later, I set "LogService.setStreamingLogLevels()" and then use "logInfo" etc.

This works well when I run the app under Yarn, all the logs show up
under the container logs but when I run the app in Standalone mode, I
can't find these logs in neither the master, worker or driver logs. So
where do they go?

Thanks,

Tim
