Sean Owen updated SPARK-16065:
------------------------------
Target Version/s: (was: 1.6.1)
Fix Version/s: (was: 1.6.1)
I can't reproduce in a similar situation. I regularly use --jars to add
third-party jars to an app and can access the class in the driver and executor.
Maybe you can double-check the classes are where you think they are.

> When run the case if we don't use the spark-submit, it can work. it is failed
> if use spark-submit and the jar included the Record is in "--jars".
> Then I did a simple testing and write below small program in main to test it.
> when readObject, the exception happened. and it is wrote into file
> successfully.
