Я хочу работать с моей базой данных postgres и sqoop. Я хотел бы получить список всех таблиц базы данных, и я хотел бы импортировать таблицу из postgresql в sqoop.
Я использую:
postgresql: 8.4.20
cloudera: Hadoop 2.6.0-cdh5.10.0
драйвер postgresql: postgresql-8.4-703.jdbc4.jar
Я использовал следующую команду для получения информации о таблицах:
sqoop import --driver postgresql-8.4-703.jdbc4.jar --connect jdbc:postgresql://0.0.0.0:7432/scm --table xx--username xx--password xx
Но я получаю сообщение об ошибке:
Warning: /usr/lib/sqoop/../accumulo does not exist! Accumulo imports will fail.
Please set $ACCUMULO_HOME to the root of your Accumulo installation.

Я пробовал также следующий драйвер коммандо:
--driver org.postgresql.Driver
Но я получаю сообщение об ошибке:

Я также пытался включить '? Sslmode = require', но он не работает.
Кто-нибудь знает, как я могу решить эту проблему?
С наилучшими пожеланиями
