Raghu Angadi updated HADOOP-5961:
---------------------------------
Description:
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.
