無法連接到蜂巢蜂巢2

Question

Hadoop 2.7.3和Hive 2.1.0

我可以像這樣連接到直線

！連接jdbc：hive2：//

但是當我打字

！connect jdbc：hive2：//主機名：10000 /默認org.apache.hive.jdbc.HiveDriver或！connect jdbc：hive2：//主機名：10000 /默認

輸入用戶名和密碼后，出現錯誤

錯誤：無法打開與jdbc：hive2：//：10000的連接：java.net.ConnectException：連接被拒絕（狀態= 08S01，代碼= 0）

在CLI中：

有什么建議么？？

我為hive 2設置的hive-site.xml中的屬性是：-

有什么建議么？

Answer 1

1. 首先，請檢查您的配置單元服務器是否正在偵聽端口10000？

   netstat -an | grep 10000

   如果不！ 轉到/tmp/{username}/hive.log ，看看有什么問題！

2. 如果hive服務器已啟動並正在運行，請檢查創建的架構！

   schematool -validate -dbType -verbose

   如果架構有問題，則應再次初始化架構。

3. 如果一切正常，則應使用以下命令進行連接：

   直線-u jdbc：hive2：// {IP或服務器名稱}：10000

Answer 2

從錯誤：

16/10/25 18:07:11 [main]: WARN jdbc.HiveConnection: Failed to connect to 10.1.1.60:1000
Error: Could not open client transport with JDBC Uri: jdbc:hive2://10.1.1.60:1000/;transportMode=binary: java.net.ConnectException: Connection refused (state=08S01,code=0)

看起來您正在連接端口1000，而不是10,000-如果您連接到端口10000，是否可以正常工作？

如果仍然無法在端口10000上運行，則確定Hiveserver2正在該端口上偵聽嗎？ 您是否可以在Hiveserver2主機上運行以下命令，並確保端口上正在偵聽某些內容：

netstat -an | grep 10000
