我们有来自Hbase的Hive。然后我使用java客户端从hive查询数据。我遇到了这个例外：

我将所有jar（在％HIVEPATH％/ lib中）添加到我的类路径中，我的代码是：
import java.sql.SQLException;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.DriverManager;
public class HiveConnect {
private static String driverName =
"org.apache.hive.jdbc.HiveDriver";
public static void main(String[] args)
throws SQLException {
try {
Class.forName(driverName);
} catch (ClassNotFoundException e) {
e.printStackTrace();
System.exit(1);
}
Connection con = DriverManager.getConnection(
"jdbc:hive2://10.0.2.6:10000/nuoyuan", "hive", "Hd@!2017");
Statement stmt = con.createStatement();
String tableName = "zm_info";
// show tables
String sql = "show tables '" + tableName + "'";
System.out.println("Running: " + sql);
ResultSet res = stmt.executeQuery(sql);
if (res.next()) {
System.out.println(res.getString(1));
}
// describe table
sql = "describe " + tableName;
System.out.println("Running: " + sql);
res = stmt.executeQuery(sql);
while (res.next()) {
System.out.println(res.getString(1) + "\t" + res.getString(2));
}
sql = "select * from " + tableName;
res = stmt.executeQuery(sql);
while (res.next()) {
System.out.println(res.getString(1));
}
}
非常感谢任何人帮我解决这个问题。
