在hive中运行HQL时抛出的异常

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了在hive中运行HQL时抛出的异常相关的知识，希望对你有一定的参考价值。
我想运行一个select语句并将结果放入表中，我确定它不是语法错误。
HQL：
INSERT overwrite table datalake_rci.MID_DealerVehicleOutputValue
--MIDDealerVehicleOutputValueID int,
select
b.MIDDealerVehicleOutputValueID
,b.DealerID --string,
,b.CHASSIS --string,
,b.DIMDealerID --bigint,
,b.DIMVehicleID --bigint,
,case when a.DIMDealerID is not null
then 1 else b.DIMOutputValueID
end DIMOutputValueID --int
,b.OutputValueName --string,
,b.OutputValueName_CN --string,
,b.OutputValueCode --varchar(50),
,b.OutputValueOrder --int
from datalake_rci.MID_DealerVehicleOutputValue b
left outer join
(
select w.low,w.DIMDealerID, w.DIMVehicleID,w.OutputValueOrder,w.row_num from (
select z.low,z.DIMDealerID, z.DIMVehicleID, z.OutputValueOrder,
row_number() over(partition by z.DIMDealerID order by z.OutputValueOrder desc) row_num
from
(
select t1.low,y.DIMDealerID, y.DIMVehicleID, y.OutputValueOrder
from
(
select b.DIMDealerID, b.cnt*l.Rate low
from
(select DIMDealerID, count(*) cnt
from datalake_rci.MID_DealerVehicleOutputValue
group by DIMDealerID) b
cross join
(select Rate from datalake_rci.DIM_OutputValue where OutputValueCode = 'Low') l
) t1
inner join
(select DIMDealerID, DIMVehicleID, OutputValueOrder
from datalake_rci.MID_DealerVehicleOutputValue) y
on t1.DIMDealerID = y.DIMDealerID
) z
) w
where w.row_num <= w.low
) a on b.DIMDealerID = a.DIMDealerID;
然后我得到以下输出：

我试了两次，但得到了同样的结果。顺便说一句，MID_DealerVehicleOutputValue表中总共有336258079行。这会导致错误吗？其他一些类似的语句在此之前成功运行，但没有多少行要处理。
答案
在进行任何内存调整之前，请尝试以更好的方式重写查询。它执行额外的连接不必要的工作。首先，您可以通过使用子计数删除不必要的内连接来大大简化它，在子计数中计算count（*）。使用解析count(*) over(partition by DIMDealerID)代替：
INSERT overwrite table datalake_rci.MID_DealerVehicleOutputValue
--MIDDealerVehicleOutputValueID int,
select
b.MIDDealerVehicleOutputValueID
,b.DealerID --string,
,b.CHASSIS --string,
,b.DIMDealerID --bigint,
,b.DIMVehicleID --bigint,
,case when a.DIMDealerID is not null
then 1 else b.DIMOutputValueID
end DIMOutputValueID --int
,b.OutputValueName --string,
,b.OutputValueName_CN --string,
,b.OutputValueCode --varchar(50),
,b.OutputValueOrder --int
from datalake_rci.MID_DealerVehicleOutputValue b
left outer join
(
select w.low,w.DIMDealerID, w.DIMVehicleID,w.OutputValueOrder,w.row_num from
(
select z.low,z.DIMDealerID, z.DIMVehicleID, z.OutputValueOrder,
row_number() over(partition by z.DIMDealerID order by z.OutputValueOrder desc) row_num
from
(
select DIMDealerID, DIMVehicleID, OutputValueOrder,
count(*) over(partition by DIMDealerID) * l.Rate low
from datalake_rci.MID_DealerVehicleOutputValue
cross join
(select Rate from datalake_rci.DIM_OutputValue where OutputValueCode = 'Low') l
) z
) w
where w.row_num <= w.low
) a on b.DIMDealerID = a.DIMDealerID;
并且作为查询优化的下一步尝试删除不必要的left join。像这样：
INSERT overwrite table datalake_rci.MID_DealerVehicleOutputValue
--MIDDealerVehicleOutputValueID int,
select
s.MIDDealerVehicleOutputValueID
,s.DealerID --string,
,s.CHASSIS --string,
,s.DIMDealerID --bigint,
,s.DIMVehicleID --bigint,
,case when s.row_num <= s.low --you do not need join to calculate this
then 1 else s.DIMOutputValueID
end DIMOutputValueID --int
,s.OutputValueName --string,
,s.OutputValueName_CN --string,
,s.OutputValueCode --varchar(50),
,s.OutputValueOrder --int
from
(
select s.low,s.DIMDealerID, s.DIMVehicleID, s.OutputValueOrder, s.MIDDealerVehicleOutputValueID,s.DealerID,s.CHASSIS,s.OutputValueName, s.OutputValueName_CN,s.OutputValueCode,s.OutputValueOrder
row_number() over(partition by s.DIMDealerID order by s.OutputValueOrder desc) row_num
from
(
select s.DIMDealerID, s.DIMVehicleID, s.OutputValueOrder, s.MIDDealerVehicleOutputValueID,s.DealerID,s.CHASSIS,s.OutputValueName, s.OutputValueName_CN,s.OutputValueCode,s.OutputValueOrder
count(*) over(partition by DIMDealerID) * l.Rate low
from datalake_rci.MID_DealerVehicleOutputValue s
cross join
(select Rate from datalake_rci.DIM_OutputValue where OutputValueCode = 'Low') l
) s
) s; --one or two subqueries also can be removed
当然我的查询可能包含一些错误，应该仔细测试，但我希望你有这个想法。几乎总是可以消除自联接。最后，您的查询只会读取每个表一次，并且将消除许多其他繁重的步骤。我希望你能摆脱至少两个reducer和两个mapper顶点。
另外我建议增加mapper并行度。调整这些设置，尝试减少数字，直到您运行更多的映射器：
--tune mapper parallelizm
set hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat;
set tez.grouping.max-size=67108864;
set tez.grouping.min-size=32000000;
另一答案
您应该更改mapreduce.reduce.shuffle.memory.limit.percent的值。
此参数用于单个shuffle（从单个Map任务复制的输出）应采用的上述内存缓冲区的最大百分比。高于此大小的shuffle大小不会被复制到内存缓冲区，而是直接写入reducer的磁盘。
尝试减少此参数的值，然后再次运行查询。
还要确保mapreduce.reduce.shuffle.merge.percent的值低于mapreduce.reduce.shuffle.memory.limit.percent
