Geting exception while using DistributedCache in Hadoop

I have used below mentioned code for Distributed Caching in main class.

job.addCacheFile(new URI(args[2]));

Below mentioned code is in reduce class.

@Override
        protected void setup(Reducer<LongWritable, Text, Text, Text>.Context context) throws IOException, InterruptedException {
            super.setup(context);
            URI[] paths = context.getCacheFiles();
            if (paths.length > 0) {
                loadDeliveryStatusCodes(paths[0].toString());
            }
        }
        private void loadDeliveryStatusCodes(String file) {
            String strRead;
            BufferedReader reader = null;
            try {
                reader = new BufferedReader(new FileReader("./some"));
                while ((strRead = reader.readLine()) != null) {
                    String splitarray[] = strRead.split(",");
                    deliveryCodesMap.put(splitarray[0].trim(), splitarray[1].trim());
                }
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                try {
                    reader.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

I am getting below mentioned exception.

@@@@@@@@/user/DeliveryStatusCodes.txt 1

Your help will save my day. Thanks.

It looks like you're missing the #some from end of your args[2].At the moment you have /user/DeliveryStatusCodes.txt, but you should have

/user/DeliveryStatusCodes.txt#some

Without it, FileReader is literally looking for ./some, which of course won't exist.

Or you can skip the alias (it's optional) and write

new FileReader("/user/DeliveryStatusCodes.txt")
