Hi,
I'm confused with saveAsNewAPIHadoopFile and saveAsNewAPIHadoopDataset. What's the difference between the two? What's the individual use cases of the two APIs? Could you describe the internal flows of the two APIs briefly? I've used Spark several months, but I have no experience on MapReduce programming. (I've read a few book chapters on MapReduce, but actually not written code myself.) So maybe this confusion comes from my lack of experience on MapReduce programming. (I hoped it won't necessary to have since I could use Spark.) Thanks.
