Well it looks like the codegen creates a `new SparkConf()`, instead of
deserializing a "broadcasted" one.
I've tried adding the registrator configuration as a System parameter (-D), but
it didn't catch. Is the generated code executed in the JVM ? in the same one if
running in standalone ?

> Dataset kryo encoder fails on Collections$UnmodifiableCollection
> ----------------------------------------------------------------
>
> Key: SPARK-15489
> URL: https://issues.apache.org/jira/browse/SPARK-15489
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.1
> Reporter: Amit Sela
>
> When using Encoders with kryo to encode generically typed Objects in the
> following manner:
> public static <T> Encoder<T> encoder() {
> return Encoders.kryo((Class<T>) Object.class);
> }
> I get a decoding exception when trying to decode
> `java.util.Collections$UnmodifiableCollection`, which probably comes from
> Guava's `ImmutableList`.
> This happens when running with master = local[1]. Same code had no problems
> with RDD api.
