--------------------------------
Hi [~gsomogyi],
I'm really sorry that I didn't update for this issue. In fact I re-tested the
registration of inner class KryoRegistrator by creating something myself and on
local spark, it does work well.
Later I changed the environment and ran it again with success. I think it
should be some classpath related problems on my side.
Regards

> When I created the _SparkConf_, I use _registerKryoClasses_ method to
> register some custom classes that I created. But when these classes are inner
