Multiple metrics emite at the same time causes logger to print corrupted metrics
--------------------------------------------------------------------------------

                 Key: CHUKWA-574
                 URL: https://issues.apache.org/jira/browse/CHUKWA-574
             Project: Chukwa
          Issue Type: Bug
          Components: input tools
         Environment: Java 6, Mac OS X 10.6
            Reporter: Eric Yang
            Assignee: Eric Yang
             Fix For: 0.5.0


Log4JMetricsContext only has synchronized locks to initialize the logger.  When they are multiple
threads trying to emite metrics, there is a slight possibility that the output of multiple
metrics written as one log entry.  Synchronized locks should apply for the whole emiteRecord
method.
