我是Hadoop/Hive的新手。我正在嘗試使用hive處理xml文件。搜索一段時間後，我遇到了可用於此目的的自定義FileFormat代碼，用於xml文件。使用自定義文件格式讀取配置單元中的xml文件
（這裏是定製xmlinputformat類的源代碼：XmlInputFormat.class
我添加xmlinputformat類罐和創建了一個示例表：
create table person (
name string
)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
STORED AS INPUTFORMAT 'com.hadoop.xmlparser.XmlInputFormat'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat';
我試圖檢索來自數據上述表，並得到了如下錯誤：從org.apache.hadoop.hive.ql.exec.MapRedTask
執行錯誤，返回碼2
繼在JobTracker的日誌中發現的錯誤：
java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
