I'm running sbt behind a proxy (with configuration in a file in sbt's conf), and it is to unable to resolve certain org.apache.hadoop#hadoop-mapreduce-client* dependencies:
[error] (*:update) sbt.ResolveException: unresolved dependency: org.apache.hadoop#hadoop-mapreduce-client-app;2.3.0: not found
[error] unresolved dependency: org.apache.hadoop#hadoop-mapreduce-client-core;2.3.0: not found

This is my sbt.build file
name := "SparkSandbox"
version := "0.1"
scalaVersion := "2.11.7"
libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "1.5.1"
libraryDependencies += "org.apache.hadoop" % "hadoop-client" % "2.3.0"
libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.5"
I have run sbt clean and sbt update, as recommended here. My repositories file looks as described here.
However, it's still stuck when I try to compile because it cannot resolve the dependencies. What am I missing?

sbt尊重http代理设置的常用环境变量：
export JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=yourserver -Dhttp.proxyPort=8080 -Dhttp.proxyUser=username -Dhttp.proxyPassword=password"
（当然，假设是Unix（ Linux / OSX等）。在Windows上你可以像往常一样设置相同的环境变量（％JAVA_OPTS％） Windows方式。）

我可以解决此问题。请停止所有的守护，然后重新开始。以下是我在快速启动VM中遵循的步骤。
1.sudo service hadoop-master stop
2.sudo service hadoop-master start
3.hadoop dfsadmin -safemode leave
现在使用spark-shell命令启动spark。
请立即运行您的火花程序。
