Answer 1

1. 就基本目錄確保運行Ant

2. 然後打開：PigBank\contrib\piggybank\java\src\main\java\org\apache\pig\piggybank\evaluation\IsInt.java和編輯行31：

   29 /** 
   30 * This UDF is used to check whether the String input is an Integer. 
   31 * Note this function checks for Integer range −2,147,483,648 to 2,147,483,647. 
   32 * If range is not important, use IsNumeric instead if you would like to check if  a String 33 is numeric. 
   34 * Also IsNumeric performs slightly better compared to this function. 
   35 */ 
   

   1. 只是刪除關於第48欄的不可打印字符並保存文件。
   2. 再次運行ant命令。
