Apache spark 在使用lucene stratio索引查询重数据集时，无法获取广播\u 0的广播\u片段0

我做了一个spark工作，在cassandra上查询lucene startio索引，并对加载的数据集进行一些处理

当数据集很大时，作业会给出一个错误，我得到以下堆栈跟踪

没有执行groupBy、collect或count。
作业从cassandra表加载数据，然后forEach触发一些删除和插入操作

使用spark submit运行它

没有使用广播变量。转换中使用的最终变量 相反

使用独立群集模式spark:spark-1.6.1-bin-hadoop2.6

我在Spark JDBC中也遇到了这个问题。如果有人能解决这个问题那就太好了。@sidd.v29你解决这个问题了吗？@semsorock，我没有解决这个问题。幸运的是，这个项目被废弃了。您可以检查：它是否解决了您的问题。不管是什么情况，一定要让我们知道结果如何。
