eclipse配置hadoop的錯誤

配置好eclipse，在執行run on hadoop的時候，提示
11/03/29 16:47:59 WARN conf.Configuration: DEPRECATED: hadoop-site.xml found in the classpath. Usage of hadoop-site.xml is deprecated. Instead use core-site.xml, mapred-site.xml and hdfs-site.xml to override properties of core-default.xml, mapred-default.xml and hdfs-default.xml respectively

補充：1. eclipse已經連接上hdfs，文件夾也上傳至hdfs中
            2. hdfs的安全模式也已經取消，hadoop dfsadmin -safemode leave
            3. 在運行配置的時候，名稱用的也不是localhost（localhost鏈接不上hdfs），用的是機器名稱
            4.hadoop已經配置好，wordcount程序在命令行裏能成功運行，個人hadoop的是徹底分佈模式，1個namenode，4個datanode

 

問題終於解決了！困擾我很久的問題啊！解決方法：
將eclipse運行配置中的arguments中 hdfs://localhost:9000/user/lxz/testin hdfs://localhost:9000/user/lxz/testout
改成：
hdfs://lxz-pc:9000/user/lxz/testin hdfs://lxz-pc:9000/user/lxz/testout
即：把localhost改成你的namenode的機器名，改成ip不行，我試過
但願能幫助到和我遇到了一樣問題的朋友！

 

mac主機名在 系統偏好設置->共享中設置:XXX.local

在終端上能夠用 uname -n或hostname -f的方式來查看

 

Arguments配置：

hdfs://ruancc.local:9000/Users/mac/wordcount.txt hdfs://ruancc.local:9000/Users/mac/output

 

ToolRunner與eclipse hadoop 插件的替代品，簡化M/R程序的開發
