我正在使用Hive来解析xml文件,因为我使用的是hivexmlserde。 当我写我的代码并执行它时,我得到错误。在Hive中解析xml时出错
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
,但我的列数和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;
