// if the plan path hasn't been initialized just return, nothing to clean.

 // if the plan path hasn't been initialized just return, nothing to clean.
 if (mapPath == null  reducePath == null) {
   return;
 }
 try {
   FileSystem fs = mapPath.getFileSystem(conf);
 {code}
 If mapPath is null but reducePath is not null, getFileSystem() call would 
 produce NPE
