Subject [jira] [Commented] (HADOOP-7436) Bundle Log4j socket appender Metrics plugin in Hadoop
Date Tue, 22 May 2012 23:56:42 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13281324#comment-13281324
] 

Luke Lu commented on HADOOP-7436:
---------------------------------

IMO, We should avoid referencing chukwa in these patches, as they're just generic SocketSinks
to send metrics as JSON, even though they're originally from chukwa.

> 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 other monitored hadoop cluster by moving the plugin code into hadoop code base.
 It is similar to bundling Ganglia metrics plugin in Hadoop code base.
