Simba][ImpalaJDBCDriver](500151) 在 Imapala jdbc 连接中设置/关闭会话时出错

Question

我正在尝试使用 JDBC 连接来连接到 impala。使用的 Imapala 驱动程序 jar 是 impalaJDBC41。创建连接对象“con”时发生错误错误是 -[Simba]ImpalaJDBCDriver 在 Imapala jdbc 连接中设置/关闭会话时出错

代码如下：

import java.sql.Connection;    
import java.sql.DriverManager;

import java.sql.SQLException;
import java.sql.Statement;

public class JDBC_Connection1 {
    private static String driverName = "com.cloudera.impala.jdbc41.Driver";
    public static void main(String[] args) throws SQLException {
    try {
       Class.forName(driverName);

        } 
   catch (ClassNotFoundException e)
       {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.exit(1);
        }
         Connection con =   DriverManager.getConnection("jdbc:impala://host:25004/;principal=impala/host@abc.ENTERPRISENET.ORG");
         Statement stmt = con.createStatement();
         String tableName = "yogesh";
         stmt.executeQuery("drop table " + tableName);
    }

}

Answer 1

url 应为：jdbc:impala://192.168.8.183:21050;AuthMech=1;KrbRealm=abc.ENTERPRISENET.ORG;KrbHostFQDN=您的主机;KrbServiceName=impala

并且 kerberos 需要 hadoop kerberos env

System.setProperty("sun.security.krb5.debug", "false");
System.setProperty("java.security.krb5.conf",loader.getResource("secret/krb5.ini").getPath());
org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
conf.set("hadoop.security.authentication", "Kerberos");
UserGroupInformation.setConfiguration(conf);
UserGroupInformation.loginUserFromKeytab("hdfs/admin@HADOOP.COM", loader.getResource("secret/184_hdfs.keytab").getPath());
        UserGroupInformation loginUser = UserGroupInformation.getLoginUser();
        loginUser.doAs(new PrivilegedAction<Void>() {
            @Override
            public Void run() {
                connectImpala();
                return null;
            }
        });
}
