Description

Currently, even the logManager is not created, we still see the log entry

s"Writing to log $record"

because of the following lines

ReceivedBlockTracker.scala

/** Write an update to the tracker to the write ahead log */
  private def writeToLog(record: ReceivedBlockTrackerLogEvent) {
    logDebug(s"Writing to log $record")
    logManagerOption.foreach { logManager =>
        logManager.writeToLog(ByteBuffer.wrap(Utils.serialize(record)))
    }
  }
