hive查询一个奇怪的问题

为了实现hive表的更新操作，我创建了一个与表test结构相同的支持事务的表acidtest（按照官网说明此表必需分桶），另外这两个表都按日期进行了分区。创建完acidtest后，我把test表数据按照分区挨个导进去，一开始acidtest的更新查询都没问题，可是当数据导入一定量后查询就开始报错，另外我发现只要把查询条件中再指定上分区就没问题了。报错信息如下（其中ArrayIndexOutOfBoundsException: 36是因为我的表不算分区列总共有35列）：

下面两个设置了吧
[mw_shl_code=bash,true]hive>set hive.vectorized.execution.enabled=false;
hive>set hive.vectorized.execution.reduce.enabled=false;[/mw_shl_code]

设置了之后确实可以了，不过大侠能解释下为什么会这样吗？
