Yu LIU created SPARK-22507:
------------------------------
Summary: Cannot register inner class with Kryo using SparkConf
Key: SPARK-22507
URL: https://issues.apache.org/jira/browse/SPARK-22507
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.6.0
Reporter: Yu LIU
Priority: Critical
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:
{noformat}
[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
