org.roaringbitmap.RoaringArray$Element is no longer present. The following
stack trace appears:

> Driver program has to register roaring bitmap classes used by spark with Kryo
> when number of partitions is greater than 2000
> ----------------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-5949
> URL: https://issues.apache.org/jira/browse/SPARK-5949
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.2.0
> Reporter: Peter Torok
> Assignee: Imran Rashid
> Labels: kryo, partitioning, serialization
> Fix For: 1.4.0
>
>
> When more than 2000 partitions are being used with Kryo, the following
> classes need to be registered by driver program:
> - org.apache.spark.scheduler.HighlyCompressedMapStatus
> - org.roaringbitmap.RoaringBitmap
> - org.roaringbitmap.RoaringArray
> - org.roaringbitmap.ArrayContainer
> - org.roaringbitmap.RoaringArray$Element
> - org.roaringbitmap.RoaringArray$Element[]
> - short[]
> Our project doesn't have dependency on roaring bitmap and
> HighlyCompressedMapStatus is intended for internal spark usage. Spark should
> take care of this registration when Kryo is used.
