向HDFS上的hive中load本地文件

public static void loadData2Hive(String dst,String dateString) {
        String JDBC_DRIVER = "org.apache.hive.jdbc.HiveDriver";
        String CONNECTION_URL = "jdbc:hive2://xx.xx.xx.xx:10000";
        String username = "";
        String password = "";
        Connection con = null;
        Statement stmt = null;

        try {
            Class.forName(JDBC_DRIVER);
            con = (Connection) DriverManager.getConnection(CONNECTION_URL,username,password);
            stmt = con.createStatement();
            String sql = "load data local inpath '" + dst + "' into table test_databse.test_table PARTITION (dt = '"+dateString+"')";
            stmt.execute(sql);
            System.out.println("loadData到Hive表成功！");
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }finally {
            // 关闭stmt和con
            if (stmt!= null){
                try {
                    stmt.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
            if(con != null){
                try {
                    con.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }

直接替换你的host的ip与你的表名和库名就可以了

需要用到的依赖，注意hive的版本hadoop的版本要对应，不然会报错
