当我尝试运行示例时，它显示了一些异常。我参考了以下链接以供参考
http://docs.mongodb.org/ecosystem/tutorial/getting-started-with-hadoop/
例外情况如下，

基本上，错误消息告诉您脚本在hadoop.gradle的第96行失败。如果您查看这个文件（本地或mongodb github上），您会发现它正试图删除hadoop-tmpdir。错误消息进一步告诉您，它无法解析传递给文件的要删除的参数。
请注意，github上最近的提交称为"Fix gradle delete for hadoop-tmpdir"
请尝试编辑您的hadoop.gradle以匹配当前在git上签入的hadoop.gradle。
