HBase MapReduce with setup function problem

[daidong]

Dear all,

  I am writing a MapReduce application processing HBase table. In each map,
it needs to read data from another HBase table, so i use the 'setup'
function to initialize the HTable instance like this:

@Override

    public void setup(Context context){

      Configuration conf = HBaseConfiguration.create();

      try {

       centrals = new HTable(conf, "central".getBytes());

      } catch (IOException e) {

      }

      return;

    }

But, when i run this mapreduce application, it is always stay in 0%,0%. And
the map phase is always under initializing, does not progress. I have
googled it, but still do not have any ideas.

P.S. I use hadoop-1.1.2 and Hbase-0.96.

Thanks!
