metrics2 not working

[tejas]

Hi

I set up hadoop 0.23. I configured hadoop-metrics.properties as well as 
hadoop-metrics2.properties to dump metric files.
However i see that hadoop still does not pick the metrics2 property file 
and still logs as per the configurations in hadoop-metrics-properties

Is there some specific configuration that i have to make to toggle the 
metric2 package?

Thanks
