我正在尝试在一台Mac上运行Playframework + Spark Master / Worker上的Spark工作。

当工作开始时，我遇到了java.lang.ClassNotFoundException。

你会教我如何解决它吗？

Here is code in Github

Envrionments：

Mac 10.9.5
Java 1.7.0_71
Play 2.2.3
Spark 1.1.1

设置历史记录：

> cd ~
> git clone git@github.com:apache/spark.git
> cd spark
> git checkout -b v1.1.1 v1.1.1
> sbt/sbt assembly
> vi ~/.bashrc
export SPARK_HOME=/Users/tomoya/spark
> . ~/.bashrc
> hostname
Tomoya-Igarashis-MacBook-Air.local
> vi $SPARK_HOME/conf/slaves
Tomoya-Igarashis-MacBook-Air.local
> play new spark_cluster_sample
default name
type -> scala

运行历史记录：

> $SPARK_HOME/sbin/start-all.sh
> jps
> which play
/Users/tomoya/play/play
> git clone https://github.com/TomoyaIgarashi/spark_cluster_sample
> cd spark_cluster_sample
> play run

错误追踪：

我在示例应用程序中找到了您的最后一次提交。 https://github.com/TomoyaIgarashi/spark_cluster_sample/commit/5e16a4d9291e83437ce2e80015bb6558df6e7feb 那是否修复了类未找到的异常？使用相同的方法添加jar后，我遇到了其他一些NullPointer问题。谢谢！
