Examples of MROutputFiles

org.apache.hadoop.mapred.MROutputFiles
Manipulate the working area for the transient store for maps and reduces. This class is used by map and reduce tasks to identify the directories that they need to write to/read from for intermediate files. The callers of these methods are from the Child running the Task.

    LocalDirAllocator lda = new LocalDirAllocator(MRConfig.LOCAL_DIR);

        null, null, new Progress(), new MROutputFiles());
    
    // write map outputs
    Map<String, String> map1 = new TreeMap<String, String>();
    map1.put("apple", "disgusting");
