hadoop-metrics.properties has double meaning in chukwa
------------------------------------------------------
Key: CHUKWA-315
URL: https://issues.apache.org/jira/browse/CHUKWA-315
Project: Hadoop Chukwa
Issue Type: Bug
Components: build and test code
Affects Versions: 0.2.0
Environment: Redhat EL 5.1, Java 6
Reporter: Eric Yang
"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.
