为什么不能正确运行shell文件，但是linux终端下面可以正确运行shell文件？

Question

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();         } Shell文件如下： #!/bin/sh bin/hadoop fs -mkdir input bin/hadoop fs -put input1.txt input 

Answer 1

1.rt.exec(str)这个运行时的环境变量和你在Linux下的环境变量可能不一样。 
2.rt.exec(str)这个子进程可能没有权限访问/usr/hadoop-0.19.0/bin/load.sh这个shell文件

Answer 2

是你的目录不对，用绝对路径
