Description

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.)
