Look into making FluoConfiguration Serializable

[keith-turner]

Was looking into writing a Spark code using Fluo. I was expecting FluoConfiguration to be serializable and it was not.

In the next release of Fluo, FluoConfiguration will be serializable. There are many ways to work around this issue before the next release. Below is an example of one way.

void doFluoStuff(FluoConfiguration fconf, JavaRDD<?> someRdd){
  //this map is serializable
  Map<String, String> confMap = fconf.toMap();

  someRdd.foreachPartition(iter->{
    FluoConfiguration fconf = new FluoConfiguration(confMap);
    try(FluoClient client = FluoFactory.newClient(fconf)){
      //do fluo stuff
    }
  }
}
