Subject [jira] Updated: (HADOOP-5455) default "hadoop-metrics.properties" doesn't mention "dfs" context
Date Tue, 10 Mar 2009 20:48:50 GMT

Philip Zeyliger updated HADOOP-5455:
------------------------------------

    Attachment: HADOOP-5455.patch

Attaching modified hadoop-metrics.properties file.  I've not added any tests since (to me)
this is really simply a documentation improvement.

> 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.)
