如何使用eclipse來編寫和執行PIG拉丁文

Question

我想在windows中從eclipse執行Pig腳本。我跟着this link。但它不起作用。有沒有需要做任何插件？或只有pig.jar很好？

試試這個，它的工作原理

Runtime runTime = Runtime.getRuntime(); 
String pigCommand = "pig -f "+pigPath+" //pigPath must be hdfs path. 
Process proc = runTime.exec(pigCommand); 
BufferedReader bri = new BufferedReader(new InputStreamReader(proc.getInputStream())); 
BufferedReader bre = new BufferedReader(new InputStreamReader(proc.getErrorStream())); 

String line = ""; 

while ((line = bri.readLine()) != null); 
while ((line = bre.readLine()) != null);
