How to run a system command on a file in the HDFS?

Question

I have a set of files in my HDFS. I need to run a system command on all these files from java using the API. How do I do it without getting the files into the local filesystem? Is it even possible?

I am very new to Hadoop; Please explain the solutions in simple terms.

Thanks in advance.
