【问题描述】：
我正在尝试构建 Apache Spark 2.1.0 源代码，但是下面的这些错误让我感到困惑......
Hadoop 2.8.0 已安装并且正在运行 Scala 2.12.1 是在执行 Spark 安装之前安装的（这似乎会自动安装 Scala 2.11.8 ?!?）
我的构建线是：
build/mvn -Pyarn -Phadoop-2.7 -Dhadoop.version=2.7.0 -DskipTests clean package
有人知道我为什么会得到：
user@server:/usr/local/share/spark/spark-2.1.0$ sudo /usr/local/share/spark/spark-2.1.0/build/mvn -Pyarn -Phadoop-2.7 -Dhadoop.version=2.7.0 -DskipTests clean package

我手动测试了下载（查看是否导致错误），下载没有问题：
https://repo1.maven.org/maven2/org/apache/apache/14/apache-14.pom
我还测试了访问下面的 URL，它也显示了内容：
https://repo1.maven.org/maven2
希望聪明人知道如何解决这个问题...
