code: @Override
  	public void configure(Configuration parameters) {
  		table = createTable();
  		if (table != null) {
  			scan = getScanner();
  		}
  	}
docs: Creates a {@link Scan} object and opens the {@link HTable} connection.
  These are opened here because they are needed in the createInputSplits
  which is called before the openInputFormat method.
  So the connection is opened in {@link #configure(Configuration)} and closed in {@link #closeInputFormat()}.
