sqoop可以将配置单元表导出到postgres或任何其他数据库吗？我可以将csv文件导出到postgres数据库。我正在尝试导出配置单元parqure格式表。
我试过以下命令

sqoop export --connect jdbc:postgresql://myhost:myportnumber/my_table --username my_user --password my_pwd  --columns id,last_updated_ts --export-dir "hdfs:///my_path/my_table" --table my_table -- --schema my_schema --validate --validator org.apache.sqoop.validation.RowCountValidator --validation-failurehandler org.apache.sqoop.validation.AbortOnFailureHandler

我得到以下错误。
