Requesting to make the Comparators and Cleaners Serializable

[larsga]

I assume this means with their configuration and all? Is there any specific use case you have in mind? I'm not against it, just curious.

Could you make a pull request for it?

In my previous project we try to use it in Apache Spark and we use scala. Since the comparator and cleaner are not Serializable, we need to instantiate this in the functional block to be executed in yarn. We just want to initialize it first as one copy to be global, and it can also be used as broadcast variable in spark. Broadcast variable need to be a serializable. I will provide a pull request on my free time :)
