hdfs java file system API: creating Configuration object

I was trying to create a java program to write/read files from HDFS.

I saw some examples of Java API. With this, the following code works for me.

Configuration mConfiguration = new Configuration();
mConfiguration.set(“fs.default.name”, “hdfs://NAME_NODE_IP:9000″);

But my set up is changed to a Hadoop HA set up so hardcoded namenode addressing is not possible.

I saw some example where in we provide the path of configuration xmls like below.
mConfiguration.addResource(new Path(“/usr/local/hadoop/etc/hadoop/core-site.xml”));
mConfiguration.addResource(new Path(“/usr/local/hadoop/etc/hadoop/hdfs-site.xml”));

This code also works when running the application in the same system as of hadoop.

But it would not work when my application is not running on the same m/c as of hadoop.

So, what is the approach I should take so that the system works but direct namenode addressing is not done.

Any help would be appreciated.
