Configuration config= context.getConfiguration();
   HTable table = new HTable(config,"index");    

   context.write(key, new Text(toReturn.toString()));
        Enumeration e = temp.keys();
      Put put = new Put(Bytes.toBytes(key.toString()));
         while(e.hasMoreElements())
    {
        String val = e.nextElement().toString();
       
put.add(Bytes.toBytes("file"),Bytes.toBytes(val),
Bytes.toBytes((temp.get(val)).toString()));
       
      break;
    }
   table.put(put);
  table.flushCommits();
table.close();



This is the part of reducer code.I dont know what should i do .

Put only one, either the HTable or the output format.

Well, it doesn't. I mean, AFAIK there's no bug in the code that does
that, so it's probably your code.

Wild guess, maybe you are using your own HTable to put plus you emit a
Put in the reducer?
