PutRequest failure and error handling

[Amit Chavan]

Hello,

I am inserting records in hbase using hclient.put(PutRequest).Below is some psuedo code -

final List<Deferred<Object>> ds = new ArrayList<Deferred<Object>>();

  for(int i=0; i < 1000; i++) {

       PutRequest pr = new PutRequest()

       Deferred<Object> d = hbaseClient.put(pr);

      d.addErrback(new Callback<Exception, Exception>() {

                    @Override

                     public Exception call(Exception arg) throws Exception {

                           //handle exception here. 

                           return arg;

                    }

                });   

       ds.add(d);

 }

Deferred.grou(ds).join();

My question is - Is it possible to pin point which put request actually failed. The error callback is getting hit  and I get the exception stack trace but I need to know if I can exactly find out which put request out of the 1k put request i make fails? Is there facility in the library or the callback to tell me that?

Thanks,

Amit
