环境情况：IDEA是安装在虚拟机CentOS6.4上，整个虚拟机使用4G内存
问题：
Exception in thread “broadcast-exchange-0” java.lang.OutOfMemoryError: Not enough memory to build and broadcast the table to all worker nodes. As a workaround, you can either disable broadcast by setting spark.sql.autoBroadcastJoinThreshold to -1 or increase the spark driver memory by setting spark.driver.memory to a higher value
尝试解决：添加配置，如下图
执行还是报错：Exception in thread “main” java.lang.OutOfMemoryError: PermGen space

JVM内存不够了。。。你的虚机加大内存吧，不然你设置2G，哪里还有内存给你用呢
