Hadoop 无法将数据加载到配置单元表中
将数据加载到配置单元表时,我遇到以下错误:Hadoop 无法将数据加载到配置单元表中,hadoop,hive,hadoop2,bigdata,Hadoop,Hive,Hadoop2,Bigdata,将数据加载到配置单元表时,我遇到以下错误: "Loading data to table test.temp1 Moved: 'hdfs://mdckd.kk.hyy.com:8020/apps/hive/warehouse/test.db/temp1/000000_0' to trash at: hdfs://mdckd.kk.hyy.com:8020/user/lams/.Trash/Current Table test.temp1 stats: [numFiles=1014, numRow

Table test.temp1 stats: [numFiles=1014, numRows=0, totalSize=50113, rawDataSize=0]"
看起来我的数据将被丢弃,但我不明白为什么。请帮忙。以下是我的表定义和使用的查询:
CREATE TABLE `temp1`(
`col1` int,
`col2` int,
`col3` int,
`col4` int,
`col5` int,
`col6` int,
`col7` int,
`col8` int,
`col9` int,
`col10` int)
ROW FORMAT SERDE
'org.apache.hadoop.hive.ql.io.orc.OrcSerde'
STORED AS INPUTFORMAT
'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat'
OUTPUTFORMAT
'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat'
LOCATION
'hdfs://mdckd.kk.hyy.com:8020/apps/hive/warehouse/test.db/temp1'
TBLPROPERTIES (
'COLUMN_STATS_ACCURATE'='true',
'numFiles'='548',
'numRows'='547',
'rawDataSize'='131280',
'totalSize'='483505',
'transient_lastDdlTime'='1490261019')
INSERT OVERWRITE TABLE temp1
select * from
(
select * from tab1
union all
select * from tab2
union all
select * from tab3
union all
select * from tab4
union all
select * from tab5
)p;
表中已有的数据将被丢弃,因为这正是
OVERWRITE
的意思。如果要追加而不是截断,请使用
INSERT-INTO-TABLE
(或在较新版本中使用INSERT-INTO
)
附言
您不需要外部查询
insert into table temp1
select * from tab1
union all select * from tab2
union all select * from tab3
union all select * from tab4
union all select * from tab5
;
创建表看起来很奇怪。创建表时,不需要使用
tblproperty
