我正在使用 Hive 解析 xml 文件，因为我正在使用 hivexmlserde。 当我编写代码并执行它时，出现以下错误。
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. java.lang.RuntimeException: The number of XPath expressions does not much the number of columns
但我的列号和 xpath 表达式是相同的。
下面是我的代码:
add jar /home/cloudera/hivexmlserde-1.0.5.3.jar;
CREATE EXTERNAL TABLE INFO(
statusCode string,
title string,

)
