我是大数据世界的新手，hadoop我正在尝试在google中运行代码，它包含四个步骤，例如将数据放入hadoop文件系统中，然后向数据中添加索引，然后创建一个使用map和reduce减少数据。
我能够执行前两个步骤:
该代码使用xml来处理位置:
我使用的代码是http://asterixdb.ics.uci.edu/fuzzyjoin/
当我执行模糊连接的最后一步时，它给了我一系列错误:
从而将跟踪文件附加到:

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
最佳答案
最后，我成功运行了代码并纠正了错误。 该错误是由于在机器上本地运行mapreduce程序导致的，我将其更改为在yarn中运行，并且该代码对于所有数据类型均适用
关于java - 在Ubuntu 14.04 hadoop 2.6版的单节点群集设置中运行hadoop程序，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36383516/
