我是大数据世界的新手，hadoop我正在尝试在谷歌中运行一个可用的代码，它由四个步骤组成，例如将数据放入hadoop文件系统，然后为数据添加索引，然后主要步骤是使用map和reduce创建一个reduced数据。
我能够完成前两步：代码使用xml来处理位置：
我使用的代码是http://asterixdb.ics.uci.edu/fuzzyjoin/
当我做最后一步，即模糊连接时，它会给我一系列错误：
特此将跟踪文件附加到：

我认为这是ubuntu中hadoop的配置错误，我使用了本教程中的配置http://www.bogotobogo.com/Hadoop/BigData_hadoop_Install_on_ubuntu_single_node_cluster.php
最后我成功地运行了代码并更正了错误该错误是由于在机器中本地运行mapreduce程序引起的，我将其更改为在纱线中运行，代码对所有类型的数据都能正常工作
