> In org/apache/crunch/impl/dist/collect/PTableBase.java materializeToMap returns org.apache.crunch.materialize.MaterializableMap
object that is not serializable ergo can not be used directly in Crunch api after.
> Also it uses poor performant AbstractMap base class that could be issue is someone assumes
that this map will be very efficient lookup table (probably most common use case).
