abstract class Serializer extends AnyRef
A serializer. Because some serialization libraries are not thread safe, this class is used to create org.apache.spark.serializer.SerializerInstance objects that do the actual serialization and are guaranteed to only be called from one thread at a time.
Implementations of this trait should implement:
1. a zero-arg constructor or a constructor that accepts a org.apache.spark.SparkConf as parameter. If both constructors are defined, the latter takes precedence.
2. Java serialization interface.

Serializers are not required to be wire-compatible across different versions of Spark. They are intended to be used to serialize/de-serialize data within a single Spark application.
