请帮我解决错误：
我在运行命令hdfs namenode时使用了apache hadoop 2.5.2-格式错误如下：
STARTUP_MSG: build = https://git-wip-us.apache.org/repos /asf/hadoop.git -r cc72e9b000545b86b75a61f4835eb86d57bfafc0; compiled by 'jenkins' on 2014-11-14T23:45Z

你不是第一个提到这个问题的人。
这是因为
hadoop-common-*.jar必须包含在org.apache.commons.configuration.Configuration班级。请参考我粘贴的链接，thx，将jar作为依赖项。
