选项工厂MRocksDBFactory
，像这样使用它rocksDBBackEnd.setOptions（新的MRocksDBFactory（））。jobManager.log中的错误信息如下：

有人能帮我吗？不确定出了什么问题，但也许会有帮助。谢谢您的回复。但它似乎并没有解决我的问题，它似乎是一个序列化程序的问题。我已更改代码并在类MRocksDBFactory
中实现选项Factory接口。jobmanager.log的信息变成java.lang.ClassNotFoundException:gerryzhou.MRocksDBFactory
。最后，这是一个向flink报告的bug，这里是问题链接。
