Description

In hadoop-metrics.properties, I set mapred.class=org.apache.hadoop.metrics.ganglia.GangliaContext.

If I then get the gmond xml feed from the gmond server, I get this:

<METRIC NAME="load_one" VAL="1.04" TYPE="float" UNITS="" TN="28" TMAX="70" DMAX="0" SLOPE="both" SOURCE="gmond"/>
...
<METRIC NAME="datanode.myhostname.bytes_read" VAL="657927" TYPE="int32" UNITS="" TN="5696" TMAX="60" DMAX="0" SLOPE="both" SOURCE="gmetric"/>

Because the bytes_read metric has the datanode.hostname prefix, it will not aggregate with metrics from other hosts properly.
