> There was apatch adding kerberos metrics which included the following line in conf/hadoop-metrics.properties:
> ugi.class=org.apache.hadoop.metrics.spi.NullContext
> However to maintain consistency with dfs,jvm and mapred metrics and for documentation
purpose we should include comments in the file to include steps to enable FileContext and
GangliaContext as well. The following lines have to be included in conf/hadoop-metrics.properties:
> # Configuration of the "ugi" context for file
> #ugi.class=org.apache.hadoop.metrics.file.FileContext
> #ugi.period=10
> #ugi.fileName=/tmp/ugimetrics.log
> # Configuration of the "ugi" context for ganglia
> # ugi.class=org.apache.hadoop.metrics.ganglia.GangliaContext
> # ugi.period=10
> # ugi.servers=localhost:8649
