Subject [jira] Created: (HADOOP-5455) default "hadoop-metrics.properties" doesn't mention "dfs" context
Date Tue, 10 Mar 2009 20:44:50 GMT
default "hadoop-metrics.properties" doesn't mention "dfs" context
-----------------------------------------------------------------

                 Key: HADOOP-5455
                 URL: https://issues.apache.org/jira/browse/HADOOP-5455
             Project: Hadoop Core
          Issue Type: Improvement
          Components: documentation, metrics
            Reporter: Philip Zeyliger
            Priority: Minor


The "hadoop-metrics.properties" file that's shipped in conf/ has configuration settings for
the metrics contexts "dfs", "mapred", and "jvm".  The (trivial) patch I'm proposing is to
include default configuration for the "rpc" context as well.  RPC metrics may be useful, and
it's difficult for a user to intuit otherwise that rpc metrics even exist.  (I stumbled upon
them after exploring with JConsole and JMX.)
