SASL authentication not complete ，java操作hive报错

java.sql.SQLException: org.apache.thrift.transport.TTransportException: SASL authentication not complete

做完每一步时一定要关闭连接再开启连接，才能正常运行。比如我上一步插入数据到hive表，就需要关闭连接，重新开启连接再进行下一步hive操作。

public class FileToHive {
	public static void main(String[] args) throws Exception{

		//测试hive文件上传
		hiveUtil.getConnection();		
		//测试插入数据		
		FileToHive.excelToHive(new File("D:\\newtable.xls"),"newtable");		
	
		//查询数据
		hiveUtil.close();
		hiveUtil.getConnection();
		ResultSet rs=null;

			
	 rs=hiveUtil.find("select * from newtable");
		
		
		  while(rs.next()){
		    	 System.out.println(rs.getObject(1));
		    	 
		     }
		
		
		
		
		
	}
