將表格從postgres數據庫導入到HDFS時出錯？

我是新來的Hadoop，我使用下面的命令從Postgres數據庫導入表HDFS將表格從postgres數據庫導入到HDFS時出錯？

sqoop import --connect 'jdbc:postgresql://0.0.0.0:5432/toptal?ssl=true&sslfactory=o‌rg.postgresql.ssl.No‌nValidatingFactory' --username 'capacityprediction_user' -P --table 'raw_hd' --target-dir '/raw_hd'

我收到以下錯誤：

'0.0.0.0：5432'絕對不正確。試試真正的IP地址 –

'由：java.lang.ClassNotFoundException'引起的聽起來像你有錯誤的JAR文件 –

它看起來像某些問題你jdbc連接。 jdbc連接的常用格式如下：

jdbc:postgresql://hostname:port/dbname"
