Subject [jira] Commented: (CHUKWA-315) has double meaning in chukwa
Date Fri, 19 Jun 2009 18:36:07 GMT


Ari Rabkin commented on CHUKWA-315:

The current setup is definitely confusing.  Files that go in hadoop conf should be very clearly
separate from chukwa config files.
And it's not quite clear to me that we want anything as complicated as the Hadoop metrics
framework for monitoring chukwa.

> "" is used as the sample for collecting hadoop metrics through
chukwa.  It is also used by chukwa process to send out chukwa metrics.  Hence, when people
copy from chukwa source code, it needs to be hand modified to comment
out chukwa metrics.  When it is left in chukwa conf dir, it needs to have hadoop section commented
out.  This is not very user friendly, and should be addressed.
> I am not comfortable to use hadoop metrics context as the metrics generation tools for
chukwa.  Metrics context class is a specialized tool for hadoop to emite metrics.  By using
hadoop metrics context, It ties unnecessary component into chukwa and complicates ease of
use.  I vote to remove metrics context from chukwa.
