Flume获取Twitter数据

Question

在通过Flume获取Twitter数据时，当我启动代理时，我收到以下错误：

SELECT field1, field2, field3 
FROM table1 t1
JOIN table2 t2 ON t2.field1 = t1.field1 AND t2.field2 = t2.field2
UNION ALL
SELECT field1, field2, field3 
FROM table1 t1
JOIN table2 t2 ON t2.field1 = t1.field1 AND t2.field3 = t2.field3

我的失败可能是什么？我是Flume的绝对初学者！
