Can we somehow read from the HDFS without converting it to local?
I need to reuse the O/P of my DFS file without copying to local. Is there a
way?

Hi
You can perhaps mount the hdfs to linux fs and then read directly. Check
this link : http://wiki.apache.org/hadoop/MountableHDFS

Try using Hadoop fs -cat
E.g
Hadoop fs -cat <filename>
