将数据加载到配置单元表时,出现以下错误:
"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, numRows=0, totalSize=50113, rawDataSize=0]"
看起来我的数据要被丢弃了,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:

`col1` int,
`col2` int,
`col3` int,

表中已经存在的数据将被丢弃,因为这到底是什么
OVERWRITE
手段。如果要追加而不是截断,请使用
INSERT INTO TABLE
(或INSERT INTO
在较新版本中)。附笔。
您不需要外部查询。
