我已經爲單節點集羣安裝了Rapidminer，Radoop，Hadoop和Hive，並執行了Radoop連接並出現如下錯誤。Radoop：java.net.ConnectException：連接被拒絕：連接

這是因爲配置單元不能連接到名稱節點 - 確保所有hadoop服務已啓動並正在運行。（命令'jps'） –

你能提供更多的信息嗎？至少包括包含產生該輸出的命令似乎非常相關。 –

檢查您的端口是否需要在Radoop和RapidMiner之間建立連接。（NameNode，DataNode ...）

Hadoop是否與RapidMiner在同一個系統上運行，或者在像Azure這樣的雲中運行？你能不能與我們分享你的日誌，以便我們可以仔細觀察？
