    @chenghao-intel  The JsonRelation has another special case that it allow input paths as
empty when it takes RDD[String] as input. So HadoopFsRelation can not assume all its sub classes
must have non-empty input paths.  Maybe need to add another flag "allowEmptyInputPaths" in
HadoopFsRelation and allow its implementation to decide that.
