Akira AJISAKA updated HADOOP-10682:
-----------------------------------

    Description: 
Metrics are not output in trunk by the following configuration:
{code}
*.sink.file.class=org.apache.Hadoop.metrics2.sink.FileSink
*.period=10
namenode.sink.file.filename=namenode-metrics.out
{code}
The below change worked well.
{code}
- namenode.sink.file.filename=namenode-metrics.out
+ NameNode.sink.file.filename=namenode-metrics.out
{code}
It means that an old configuration doesn't work on trunk. We should fix it or 
document to use "NameNode".
