Subject Re: Error when set RocksDBStateBackend option in Flink?
Date Thu, 29 Jun 2017 09:53:07 GMT
Since MRocksDBFactory doesn't add any option, it
seems rocksDBBackEnd.setOptions() call can be skipped.

If you choose to keep the call, please take a look at (OptionsFactory
extends java.io.Serializable):
