Microsoft Azure HDinsight Ambari Sqoop和Postgres

Question

嘗試將數據從Postgres導入到Microsoft Azure HDInsigt上的hdfs中。 現在，如果列出數據庫，我將以一個非常簡單的命令開始

sqoop list-databases --connect jdbc.postgresql://xx.xxx.xxx.xxx:yyyy --username myuser --password mypassword

我收到以下錯誤

ERROR tool.BaseSqoopTool: Got error creating database manager: java.io.IOException: No manager for connect string: jdbc.postgresql://52.178.204.150:4321
    at org.apache.sqoop.ConnFactory.getManager(ConnFactory.java:191)

    at org.apache.sqoop.Sqoop.runTool(Sqoop.java:235)
    at org.apache.sqoop.Sqoop.main(Sqoop.java:244)

我嘗試添加以下參數

--libjars=/usr/share/java/postgresql-jdbc4.jar
--driver org.postgresql.Driver 
--connection-manager org.apache.sqoop.manager.GenericJdbcManager

這些仍然無濟於事HDInsight手冊僅舉一個使用Microsoft SQL的示例。
