我正在尝试通过配置单元来解析xml，方法是使用serde在hdfs上的xml文件上创建外部表。请在下面找到我的代码
我先加了jar

add jar hdfs://xtlinno1vftsnxg:8020/user/hdfs/hivexmlserde-1.0.5.3.jar;

CREATE EXTERNAL TABLE hive_test_xml(
. . . . . . . . . . . . . . . . . . . . . . .> col1            string,
. . . . . . . . . . . . . . . . . . . . . . .> col2            string,
. . . . . . . . . . . . . . . . . . . . . . .> col3            string)
. . . . . . . . . . . . . . . . . . . . . . .> ROW FORMAT SERDE 'com.ibm.spss.hive.serde2.xml.XmlSerDe'
. . . . . . . . . . . . . . . . . . . . . . .> WITH SERDEPROPERTIES (
. . . . . . . . . . . . . . . . . . . . . . .> "column.xpath.col1"="/book/author/text()",
. . . . . . . . . . . . . . . . . . . . . . .> "column.xpath.col2"="/book/title/text()",
. . . . . . . . . . . . . . . . . . . . . . .> "column.xpath.col3"="/book/genre/text()"
. . . . . . . . . . . . . . . . . . . . . . .> )
. . . . . . . . . . . . . . . . . . . . . . .> STORED AS
. . . . . . . . . . . . . . . . . . . . . . .> INPUTFORMAT 'com.ibm.spss.hive.serde2.xml.XmlInputFormat'
. . . . . . . . . . . . . . . . . . . . . . .> OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat'
. . . . . . . . . . . . . . . . . . . . . . .> LOCATION 'hdfs://xtlinno1vftsnxg:8020/user/poctest2/testxml2.xml'
. . . . . . . . . . . . . . . . . . . . . . .> TBLPROPERTIES (
. . . . . . . . . . . . . . . . . . . . . . .> "xmlinput.start"="<book",
. . . . . . . . . . . . . . . . . . . . . . .> "xmlinput.end"="</book>");

我得到的错误是
执行错误，从org.apache.hadoop.hive.ql.exec.ddltask返回代码1。org/apache/hadoop/hive/serde2/serde（state=08s01，code=1）
我不知道如何解决这个错误…请帮助！！
