情景

我正在尝试通过zookeepers集群将配置单元表从本地笔记本连接到远程开发服务器，并尝试更新表列值。hadoop集群和hive表也远程位于dev环境中。我正在使用hive-jdbc.jar版本2.1.0和hadoop公共版本2.7.1

发行

面临更新表记录但stmt.getupdatecount（）和stmt.executeupdate分别返回-1和0的问题。代码：有什么遗漏吗？？或者在配置单元表中getupdatecount（）的行为不同？感谢您的快速帮助。。
代码：

private static String driverName = "org.apache.hive.jdbc.HiveDriver"; 
public static void main(String[] args) throws SQLException, 
ClassNotFoundException {   
Class.forName(driverName);
Connection con = 
DriverManager.getConnection("jdbc:hive2://XXXX:XXXX/tibco,
XXXX:XXXX/tibco,XXXX:XXXX/tibco;
serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2;
"hive.execution.engine=tez", "hive", "");
Statement stmt = con.createStatement();
con.setAutoCommit(true);
System.out.println("created");
ResultSet rs = stmt.executeQuery("select * from tibco.log_events_poc");
ResultSet db1=stmt.executeQuery("desc tibco.log_events_poc");
System.out.println("tibco.log_events_poc table -->"+db1);
int rowsupdated = stmt.executeUpdate("update tibco.log_events_poc set 
name='sample1'");            
System.out.println("Number of Rows updated"+stmt.getUpdateCount());
System.out.println("Number of Rows updated"+rowsupdated);
stmt.close();           
con.close();
  }
