Agree. Your idea sounds really more concise. If you don't mind. I will start it.

> Currently, the read APIs provided by {{HadoopInputs}} only can read one path. I think it's not strong enough. We should support read a whole directory or multiple input files.
> Hadoop provides {{org.apache.hadoop.mapred.FileInputFormat.setInputPaths()}} to support this requirement.
> Spark's {{sequenceFile}} API calls this API([https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L1049].)
> Flink calls {{org.apache.hadoop.mapred.FileInputFormat.addInputPath}} which only supports one path.
