---------------------------------

+1 for this issue. 
The metric information will be very useful for various purpose such as the query optimization.

> Currently, there is no way to measure and observe Tajo's internal operations. As a Hadoop
job, Tajo also should measure and record a lot of operational works.
> I would like to propose the use of Metrics (http://metrics.codahale.com/). It is well
known as a stable and efficient metric library.
