<div class="block">:: DeveloperApi ::
 A serializer. Because some serialization libraries are not thread safe, this class is used to
 create <a href="../../../../org/apache/spark/serializer/SerializerInstance.html" title="class in org.apache.spark.serializer"><code>SerializerInstance</code></a> objects that do the actual
 serialization and are guaranteed to only be called from one thread at a time.
 <p>
 Implementations of this trait should implement:
 <p>
 1. a zero-arg constructor or a constructor that accepts a <a href="../../../../org/apache/spark/SparkConf.html" title="class in org.apache.spark"><code>SparkConf</code></a>
 as parameter. If both constructors are defined, the latter takes precedence.
 <p>
 2. Java serialization interface.
 <p>
 Note that 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.</div>
