Hyunsik Choi created TAJO-333:
---------------------------------
Summary: Add metric system to Tajo
Key: TAJO-333
URL: https://issues.apache.org/jira/browse/TAJO-333
Project: Tajo
Issue Type: Bug
Reporter: Hyunsik Choi
Fix For: 0.8-incubating
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.
