> DataNode should use ToolRunner to parse generic hadoop options (like -Dconfig.var=value).
Apart from being more consistent with rest of the hadoop programs, this is necessary to write
a simple script to run multiple datanodes on the same node.
> I had proposed a simple shell script to running multiple datanodes on a the user mailing
list http://www.nabble.com/Contributing-to-hadoop-td22198897.html, but it requires that DataNode
parses -D option.
> I will submit a patch and a shell script that works.
