java - 使用Hive SQL Java错误将CSV数据加载到表中InvocationTargetException

Question

我很疯狂，因为无法使用Hive SQL将数据加载到表中。请教我如何解决此错误

在元数据中创建表。我用2条语句:

1-创建表格:

CREATE TABLE db1.test_table_file3(
Col1 INT,Col2 SMALLINT,Col3 SMALLINT)
COMMENT 'test_table_file2'
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
LINES TERMINATED BY '\n'

2-将数据加载到表中:

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

代码如下:

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

结果如下:

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

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

Answer 1

问题在第二句话，下面是它的解释。

如果HDFS中有数据，则LOAD DATA INPATH 'hdfs:/test/test_test_5.csv' INTO TABLE
db1.test_table_file3将起作用。

如果您有本地文件，则应使用LOCAL INPATH LOAD DATA LOCAL INPATH '/test/test_test_5.csv' INTO TABLE
db1.test_table_file3

如果要从HDFS加载文件，请在文件路径前提及namenode

我建议您先从JAVA中运行第二条语句，然后看看您遇到了什么错误。人们通常会遇到外部表的权限问题，请注意，HIVE用户应该有权访问HDFS路径。

您可以引用 this页面，以非常简单的方式进行说明。

我从您的问题中注意到了另一个问题，您在表中将字段定界符设置为制表符'\ t'，并且您尝试插入CSV文件，不确定是否是您的问题样本中的错误。

如果您遇到一些错误，请对这些错误进行评论，我们将为您提供帮助。
