HBase的汉字乱码问题

运用Java的API存储汉字到hbase中，代码如下：
public static void insterRow(String tableName,String rowkey,String colFamily,String col,String val) throws IOException {
      init();
      Table table = connection.getTable(TableName.valueOf(tableName));
      Put put = new Put(Bytes.toBytes(rowkey));
      put.addColumn(Bytes.toBytes(colFamily), Bytes.toBytes(col), Bytes.toBytes(val));
      table.put(put);

      //批量插入
   /* List<Put> putList = new ArrayList<Put>();
      puts.add(put);
      table.put(putList);*/
      table.close();
      close();
}
参数直接穿得就是"参数"这种格式的
然后从Hbase中读取数据代码如下：
Table table = connection.getTable(TableName.valueOf(tableName));
      Get get = new Get(Bytes.toBytes(rowkey));
      get.addFamily(Bytes.toBytes(colFamily));
      get.addColumn(Bytes.toBytes(colFamily),Bytes.toBytes(col));
      Result result = table.get(get);
      Cell[] cells = result.rawCells();
      String str ="NULL";
      String str1 ="NULL";
      if(cells.length > 0)
        str = new String(CellUtil.cloneValue(cells[0]));
   // Bytes.toString(CellUtil.cloneValue(cells[0])+" ");
   // CellUtil.cloneValue(cells[0]).toString();
      showCell(result);
      str1 = new String(str.getBytes("gbk"), "utf-8");
      table.close();
      close();
      System.out.println( Bytes.toString(Bytes.toBytes(str)));
      System.out.println(str1);
      return str1;
获取的这个str1中控制台打印有一部分汉字是乱码有一部分是？？
