Bundle Chukwa Metrics plugin in Hadoop
--------------------------------------
Key: HADOOP-7436
URL: https://issues.apache.org/jira/browse/HADOOP-7436
Project: Hadoop Common
Issue Type: New Feature
Environment: Java 6
Reporter: Eric Yang
Assignee: Eric Yang
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.
