spark 邮件报错

在集群上跑代码，如果有问题，希望能发邮件到自己的邮箱。

想使用如下代码（环境是在win10下的intelliJ idea里，平时用sbt compile和sbt package，打成jar包后粘贴到集群spark里跑）

1：刚开始使用的时候装在的是jdk1.8，出现

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

解决方法是：

你这个是jdk导致的，jdk里面有一个jce的包，安全性机制导致的访问https会报错，官网上有替代的jar包，换掉就好了

牛逼啊包在这里 http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

目录 %JAVA_HOME%\jre\lib\security里的local_policy.jar,US_export_policy.jar

it works！

2：用sbt打过jar包放入集群里跑，出现错误

Unsupported major.minor version 52.0

上网查出是jdk1.8的原因。（没有使用最开始的那段代码的时候，是不报这个错误的）

于是在windows10安装jdk1.7，并改了环境变量。并更新了idea里的jdk版本。

但是打包后放入集群中运行依然报这个错误。

于是猜想还是使用了jdk1.8,便把jdk1.8和jre1.8都删除了（仅仅是文件夹的删除，当时是绝对可能打包的时候还是用的1.8）

再打包运行，依然报这个错误。

在cmd下运行java -version，显示系统找不到文件 C:\ProgramData\Oracle\Java\javapath\java.exe。

于是将jdk1.7中的三个exe文件的快捷方式替换C:\ProgramData\Oracle\Java\javapath\java.exe目录下的三个对应文件。

在cmd下，不显示刚才的错误，显示了另一项错误，于是将jdk1.8 jdk1.7均卸载，重新安装了jdk1.7，之后cmd下显示了java version是1.7。

于是用sbt打包，说是找不到什么java。

重启后，将idea里的有关jdk版本的都确认为jdk7。

打包后运行不报之前的错误了。

报找不到org/jsoup/jsoup类的错误。

将windows下ivy2下的对应的jar包粘贴到集群下（运行脚本同级目录下）后，就可以了。
