有些需要查询的，并不是maven库里都有的。这个maven库中所有的hadoop-common版本，并没有楼主所写的版本。所以不会下载成功的

the container maven dependencies references not existing librart  hadoop-common-2.6.0-cdh5.5.1.jar
...

首先确定有这个包，有的包可能因为各种原因下载失败。
如果是测试，可以尝试其他包，看能否下载成功。

这个设置了pom.xml，maven会自动下载的了！

是说库里没有这个包 hadoop-common-2.6.0-cdh5.5.1.jar
楼主下载这个包，然后放到库对应的路径即可
