Amit Sela updated SPARK-15489:
------------------------------
Description:
When setting a custom "spark.kryo.registrator" (or any other configuration for
that matter) through the API, this configuration will not propagate to the
encoder that uses a KryoSerializer since it instantiates with "new SparkConf()".
See:
Example:
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.
