我是一个hadoop爱好者，还处于学习阶段，出于好奇我尝试了一些东西，我想做一个servlet调用hadoop的工作。我尝试了两种方法，但都失败了。等等，首先有人能告诉我这是否可行吗？如果是这样的话，请用一些实时的例子（不要告诉我色调），或者你可以简单地告诉我，我疯了，浪费我的时间。
好吧，如果你在读这篇文章，那我没疯。现在请看看我的代码，告诉我我做错了什么！！！

方法一http状态500出错-mkdirs无法创建文件：/var/lib/tomcat7/servelets
方法2 http状态500出错-无法运行程序“hadoop fs-copyfromlocal/home/asadgenx/filelist.txt/user/asad/myfile.txt”：错误=2，没有这样的文件或目录
这里的hadoopMaven能帮我解决这个问题吗！！！
