> For monitoring hadoop cluster with Chukwa, the current step is to copy chukwa-hadoop-*-client.jar and json-simple to hadoop classpath. (i.e. $HADOOP_HOME/lib or $HADOOP_PREFIX/share/hadoop/lib), and modify the hadoop-metrics.properties to use org.apache.hadoop.chukwa.inputtools.log4j.Log4JMetricsContext for emitting metrics.  It is preferred to reduce the number of manual steps that is required to enable chukwa monitored hadoop cluster by moving the plugin code into hadoop code base.  It is similar to bundling Ganglia metrics plugin in Hadoop code base.
