将csv数据加载到表使用Hive SQL java错误InvocationTargetException

我很疯狂，因为无法将数据加载到表中使用Hive SQL。请教我如何解决这个错误

在元数据中创建表格。我用2声明：

1 - 创建表格：

LOAD DATA INPATH '/test/test_test_5.csv' INTO TABLE 
db1.test_table_file3

2 - 将数据加载到表格：

Connection con = getConnection();
Statement stmt = con.createStatement();
Statement loadDataStmt = con.createStatement();
stmt.execute(createTableQuery);
loadDataStmt .execute(loadDataSQL);
closeConnection(con, stmt);
closeConnection(con, loadDataStmt);

以下代码：

Statement 1 create table: Execute successful  
Statement 2 Load data: Execute fail  

java.sql.SQLException: java.lang.reflect.InvocationTargetException

结果如下：

      private void jButtonSaveActionPerformed(java.awt.event.ActionEventevt) 
                 {                                            
             String filePath = "C:\\Users\\Stephen\\folder\\Programming 
               Assignment copy\\doctor.txt";
    File file = new File(filePath);
    try {
        FileWriter fw = new FileWriter(file);
        BufferedWriter bw = new BufferedWriter(fw);

        for(int i = 0; i < jTableDoc.getRowCount(); i++){//rows
            for(int j = 0; j < jTableDoc.getColumnCount(); j++){//columns
                bw.write(jTableDoc.getValueAt(i, j).toString()+",");
            }
         bw.newLine();
        }

        bw.close();
        fw.close();

    } catch (IOException ex) {
        Logger.getLogger(doctorTable.class.getName()).log(Level.SEVERE, null, ex);
    }        // TODO add your handling code here:
}

答案 0 :(得分：0)

问题在于第二个陈述，以下是对它的解释。

如果您拥有HDFS中的数据，则LOAD DATA INPATH 'hdfs:/test/test_test_5.csv' INTO TABLE db1.test_table_file3将起作用。

如果您在本地拥有该文件，则应使用LOCAL INPATH LOAD DATA LOCAL INPATH '/test/test_test_5.csv' INTO TABLE db1.test_table_file3

  • 如果从HDFS加载文件，请提及文件路径前的namenode

我建议你首先从JAVA中运行第二个语句，然后看看你得到了什么错误。人们通常会遇到外部表的权限问题，请注意HIVE用户应该可以访问HDFS路径。

您可以参考init.rc页面，以非常简单的方式进行解释。

我注意到你问题中的另一个问题，你在字段中将字段分隔符设置为选项卡'\ t'，并且您正在尝试插入CSV文件，不确定它是否是您的问题示例中的错误

如果您遇到一些错误，请评论错误，我可以帮助您。
