Sanjay Radia commented on HADOOP-2645:
--------------------------------------

The MBean server doe snot cal these method automatically.
It is called on demand if a JMX client call this.

However since  JMX console has a convenient graphing tool for numeric attributes someone could
graph these it would call these methods.
I have changed these from attributes to explicit operations.
Thanks for catching this Raghu.

I was not able to reproduce the error.
