> It will throw ClassCastException when we use new input format (eg. `org.apache.hadoop.mapreduce.InputFormat`) to create HadoopRDD.So we need to use NewHadoopRDD to deal with this input format in TableReader.scala.
> Exception :
> {noformat}
> Caused by: java.lang.ClassCastException: org.apache.hadoop.mapreduce.lib.input.TextInputFormat cannot be cast to org.apache.hadoop.mapred.InputFormat
