Hive ClassNotFoundException即使所有的jar都添加到maven倉庫中

我添加了這個項目所需的所有jar，但是我無法解決這個exception。任何人都可以給出關於這個的建議。您是否也可以告訴告訴如何給予配置單元數據庫訪問權限。在此先感謝。Hive ClassNotFoundException即使所有的jar都添加到maven倉庫中

您使用的任何代碼示例？ – Yeikel

public class CreateHiveExternalTable { \t public static String driverName =「org.apache.hadoop.hive.jdbc.HiveDriver」; \t \t公共靜態無效createHiveExternalTable（）拋出FileNotFoundException異常，IOException異常，{的SQLException \t \t嘗試{ \t \t \t的Class.forName（驅動程序名）; \t \t}趕上（ClassNotFoundException的發送）{ \t \t \t // TODO自動生成的catch程序塊 \t \t \t e.printStackTrace（）; \t \t} – Yasodhara

你可以看到上面我添加的代碼 – Yasodhara

hive.server2.thrift.port是你可以檢查端口的屬性。

在蜂巢外殼給命令「設置hive.server2.thrift.port」這會給你蜂箱端口設置爲10000的蜂巢

默認的端口號，但你可以再檢查一下使用上述命令蜂巢殼..

非常感謝你 – Yasodhara

從這個帖子Connect from Java to Hive using JDBC

嘗試
private static String driverName = "org.apache.hive.jdbc.HiveDriver" 
，而不是
private static String driverName = "org.apache.hadoop.hive.jdbc.HiveDriver"; 
我希望你已經在你的代碼添加Class.forName(driverName)聲明

另外：中

Connection connect = DriverManager.getConnection("jdbc:hive2://localhost:HIVEPORT/hivedb","hive","");

代替

Connection connect = DriverManager.getConnection("jdbc:hive://localhost/hivedb","hive","");

我不知道你正在運行的端口配置單元，但記得要改變這一行

localhost:HIVEPORT

可以請你告訴我如何找到配置單元端口號，因爲直到現在我直接使用配置單元直接通過終端，但不使用java ... – Yasodhara
