Question

我正在尝试整合Hadoop和Mongo。我从git下载了mongo-hadoop文件，并尝试使用下面的方法构建jar文件。但我得到了以下错误

[krishna@localhost mongo-hadoop]$ ./gradlew jar –Phadoop_version='2.4'

FAILURE: Build failed with an exception.

* Where:
Build file '/home/krishna/mongo-hadoop/build.gradle' line: 318

* What went wrong:
A problem occurred evaluating root project 'mongo-hadoop'.
> Could not resolve all dependencies for configuration ':spark:compile'.
> Could not download artifact 'commons-math3.jar  (org.apache.commons:commons-math3:3.4.1)'
  > Could not GET 'https://repo1.maven.org/maven2/org/apache/commons/commons-math3/3.4.1/commons-math3-3.4.1.jar'.
     > Network is unreachable

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or -- debug option to get more log output.

BUILD FAILED

任何人都可以告诉我们如何解决这个问题

Answer 1

您确定有网络连接吗？

在控制台中尝试此操作以检查网络是否正常：

$ wget https://repo1.maven.org/maven2/org/apache/commons/commons-math3/3.4.1/commons-math3-3.4.1.jar

Answer 2

我的防火墙阻止了连接。所以我禁用了防火墙并重新启动了VM。现在它完美运作
