同学，: Could not resolve dependencies for project org.apache.spark:spark-launcher_2.11:jar:2.1.1: Failure to find org.apache.hadoop:hadoop-client:jar:2.6.0-cdh5.7.0 in https://repo1.maven.org/maven2 这个提示很明白了，关于spark编译不成功怎么解决，看下置顶的帖子 http://coding.imooc.com/learn/questiondetail/qid/15308，老师也有一篇手记供参考

  恩 谢谢~我下了一个hadoop-client-2.6.0-cdh5.7.0.jar 包，编译过后错误解决了
