我们曾经在hive中运行下面提到的查询并且它工作正常但是在hadoop 2.1升级之后它失败了。
insert overwrite table x
Select a.emp_id,a.emp_name,
coalesce(b.salary, 0.0),
coalesce(b.work_days, 0.0),
coalesce(c.previous_work_days, 0.0)
from a left outer join b
on (a.emp_id = b.emp_id)
left outer join x
on (a.emp_id = x.emp_id);
我发现问题就像从同一个表（x）读取并插入相同的（x）导致问题。有没有人遇到过同样的问题。
