Hi, I am trying to create a hardlink between the files created after the Map phase and the Reducer nodes which are behind Lustre. So basically the entire copy phase during shuffle is eliminated. To create these hardlinks I need the exact fully qualified filenames of the partitioned Map outputs and also the Path to the File on the Reducer node where it is copied to. I am working on hadoop-1.0.2 version and the entire process happens in the ReduceTask.java class. I see that the files on Reduce node to which data is read into is named as *output/map_1.out-2. *Is this correct? Also I couldn't find out the fully specified path of the files on Map-side i.e the names of the partitioned Map-output files. Anyone has any idea how to find out the fully qualified pathnames of these files? Any help is highly appreciated.Thanks
