Description

"hadoop-metrics.properties" 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 hadoop-metrics.properties 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.
