Question

I need to connect Hive2 and retrive information from it. I am using apache HiveServer2 client to connect to Hive, in POM:

<dependency>
    <groupId>org.apache.hive</groupId>
    <artifactId>hive-jdbc</artifactId>
    <version>1.2.1</version>
</dependency>

The code is:

public class HiveJdbcClient {
    private static String driverName = "org.apache.hive.jdbc.HiveDriver";
    public static void main(String[] args) throws SQLException {
        org.apache.log4j.BasicConfigurator.configure(new NullAppender());
         try {
              Class.forName(driverName);
            } catch (ClassNotFoundException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
              System.exit(1);
            }

         Connection con = DriverManager.getConnection("jdbc:hive2://xxx.xx.xx.xx:21050/;auth=noSasl");
         Statement stmt = con.createStatement();
         ResultSet res = stmt.executeQuery("show tables");
            if (res.next()) {
              System.out.println(res.getString(1));
            }
    }

}

But when running this app, I got this exeception:

Exception in thread "main" java.lang.NoSuchFieldError: HIVE_CLI_SERVICE_PROTOCOL_V8
    at org.apache.hive.jdbc.HiveConnection.<init>(HiveConnection.java:189)
    at org.apache.hive.jdbc.HiveDriver.connect(HiveDriver.java:105)
    at java.sql.DriverManager.getConnection(DriverManager.java:664)
    at java.sql.DriverManager.getConnection(DriverManager.java:270)
    at org.springframework.samples.hadoop.hive.HiveJdbcClient.main(HiveJdbcClient.java:23)

Can anyone tell me how this exception is thrown?

Answer 1

新版本的hive-jdbc无法与hiveserver2一起使用。在hive jira上已经有相同的错误。 https://issues.apache.org/jira/browse/HIVE-6050您可以使用hive-jdbc 1.0.0版本，它是兼容的。

Answer 2

“HIVE_CLI_SERVICE_PROTOCOL_V8”此字段在hive 1.1.0版本中可用。

你需要在classpath中添加hive-jdbc-1.1.0.jar jar。

我希望你的问题得到解决。

Apache Hive client throw NoSuchFieldError: HIVE_CLI_SERVICE_PROTOCOL_V8
