windows下eclipse远程连接hadoop错误“Exception in thread"main"java.io.IOException: Call to Master.Hadoop/172.20.145.22:9000 failed ”

在VMware虚拟机下搭建了hadoop集群，ubuntu-12.04，一台master，三台slave。hadoop-0.20.2版本。在 master机器上利用eclipse-3.3连接hadoop并运行mapreduce实例可以成功。但是当在windows下eclipse-3.3 远程连接hadoop，DFS locations可以连接上，但运行mapreduce实例时报错，如下：

13/07/02 13:37:04 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

分析原因和解决方案:

导致这个问题的原因是由于eclipse上面引入的hadoop版本和linux虚拟机上面安装的hadoop版本不一致导致，把两边环境的版本换成一致就可以了。
