我正在尝试将数据从hdfs位置导出到greenplum用户定义的模式(不是默认模式)。
尝试sqoop eval检查连接。
sqoop eval --connect "jdbc:postgresql://sample.com:5432/sampledb" --username sample_user --password xxxx --query "SELECT * FROM sample_db.sample_table LIMIT 3"
结果:工作正常
试用 --schema
选项
/usr/bin/sqoop export --connect "jdbc:postgresql://sample.com:5432/sampledb" --username sampleuser --password samplepassword --table sample_table --schema sample_schema --export-dir=/sample/gp_export --input-fields-terminated-by ',' --update-mode allowinsert
结果:
Warning: /usr/hdp/2.3.6.0-3796/accumulo does not exist! Accumulo imports will fail.
Please set $ACCUMULO_HOME to the root of your Accumulo installation.

18/06/25 11:09:41 ERROR tool.BaseSqoopTool: Unrecognized argument: allowinsert
额外增加 '--'
之前 '--schema'
基于sqoop文档https://sqoop.apache.org/docs/1.4.3/sqoopuserguide.html
/usr/bin/sqoop export --connect "jdbc:postgresql://sample.com:5432/sampledb" --username sampleuser --password samplepassword --table sample_table -- --schema sample_schema --export-dir=/sample/gp_export --input-fields-terminated-by ',' --update-mode allowinsert
结果:
Warning: /usr/hdp/2.3.6.0-3796/accumulo does not exist! Accumulo imports will fail.
Please set $ACCUMULO_HOME to the root of your Accumulo installation.

Export requires an --export-dir argument or --hcatalog-table argument.
Try --help for usage instructions.
有人能给我指点一下吗。谢谢

感谢@cricket\u 007的澄清。
--schema
参数应该是sqoop命令中的最后一个。所以下面的代码是有效的。但是
UPSERT
postgressql中不支持的操作。这里有一张开放的吉拉门票。https://issues.apache.org/jira/browse/sqoop-1270ygya80vv2#
之后
--export-dir
你不需要=
看看下面的例子。另一个建议是使用--verbose
当你遇到这些问题的时候。
