Subject [jira] [Commented] (TAJO-333) Add metric system to Tajo
Date Wed, 11 Dec 2013 10:12:08 GMT

    [ https://issues.apache.org/jira/browse/TAJO-333?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13845254#comment-13845254

Jihoon Son commented on TAJO-333:
---------------------------------

Thanks for your detailed comment!
But, I have a question for the MetricsConsoleReporter issue. 
My above comment means that the master address can be the private network address such as
192.168.0.xxx.
In that case, it seems to print the wrong host address.

> 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.
