Ich verwende Hive 2.1.1 und versuche, eine Verbindung zu erstellen. Im Anschluss ist der Code ich versuche:Hive JDBC-Verbindung NoClassDefFoundError
private static String driverName = "org.apache.hive.jdbc.HiveDriver";
public static void main(String[] args) throws SQLException, ClassNotFoundException {
// Register driver and create driver instance
Class.forName(driverName);
// get connection
Connection con = DriverManager.getConnection("jdbc:hive2://", "", "");
Statement stmt = con.createStatement();
stmt.executeQuery("CREATE DATABASE userdb");
System.out.println("Database userdb created successfully.");
con.close();
}
Diese sind meine CLASSPATHs in bashrc erklärt:
CLASSPATH=$CLASSPATH:/usr/lib/hive/lib/hive-jdbc-2.1.1.jar CLASSPATH=$CLASSPATH:/usr/local/hadoop/lib/*:. CLASSPATH=$CLASSPATH:/usr/local/apache-hive-2.1.1-bin/lib
Ich erhalte den Fehler unten.

Jede Hilfe wäre willkommen.
Verwenden Sie "hive-jdbc - ** standalone ** - 2.1.1.jar", um die Abhängigkeit Kopfschmerzen loszuwerden ... –
Vorbehalt: sogar mit der so genannten "Standalone" JAR werden Sie auch 'Hadoop benötigen -common.jar' und 'commons-configuration.jar' in CLASSPATH und möglicherweise' hadoop-auth.jar' (erforderlich für Kerberos) –
