> Hi All,
>
> I'm working on hive 0.8.1. and meet following problem.
> I use function substr(item,-4,1) to process one item in hive table, and
> there is one row in which the content of the item is
> "ba_s0一朝忽觉京梦醒，半世浮沉雨打萍--衣俊卿小n实录010", then the job failed.
> I checked the task log, it appeared
>
> java.lang.StringIndexOutOfBoundsException: String index out of range
>
> Then I tried this program on my PC,
>
>
>
> =============================================
>
> //test substring()
>
> public class substrtest {
>
> public static void main(String args[]){
> String s="ba_s0一朝忽觉京梦醒，半世浮沉雨打萍--衣俊卿小n实录010";
> int len=s.length();
> System.out.println(len);
> String r=s.substring(28, 29);
> System.out.println(r);
> }
> }
> =======================================
