JAVA调用这个SHELL文件、为什么不能运行

JAVA代码如下：
try {
            Runtime rt = Runtime.getRuntime();
           
            String str[] = {"/bin/sh", "-c", "/usr/hadoop-0.19.0/bin/load.sh"};
           
            Process pcs = rt.exec(str);
            BufferedReader br = new BufferedReader(new InputStreamReader(pcs.getInputStream()));
            String line = new String();
            if(textarea.getText()!=null)
                textarea.setText("");
            while ((line = br.readLine()) != null) {
                textarea.append(line);
                textarea.append("\n");
            
            }
            try {
                pcs.waitFor();
               
            } catch (InterruptedException e) {
                System.err.println("processes was interrupted");
            }
            br.close();
           

        } catch (Exception e) {
              e.printStackTrace();
        }

一个简单的Shell文件如下：
#!/bin/sh
bin/hadoop fs -mkdir input
bin/hadoop fs -put input1.txt input

不能正确运行shell文件，但是linux终端下面可以正确运行shell文件，本人是菜鸟，还望各位解答，谢谢。
