Description

When I created the SparkConf, I use registerKryoClasses method to register some custom classes that I created. But when these classes are inner classes, they cannot be successfully added and I got following error:

[ERROR]: org.apache.spark.scheduler.TaskSetManager - Task 0 in stage 0.0 failed 4 times; aborting job
[ERROR]: org.apache.spark.streaming.scheduler.JobScheduler - Error running job streaming job 1510585911000 ms.0
