Subject [jira] [Created] (HADOOP-7436) Bundle Chukwa Metrics plugin in Hadoop
Date Thu, 30 Jun 2011 19:43:30 GMT
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.
