-------------------------------
As I analyzed the exception stack trace again, I found the exception was thown
at NewHadoopRDD.getPartitions, when invoke inputFormat.getSplits, so I add the
similar modification as SPARK-1203 there, as running for so long time, never
occur again.
> when use saveAsNewAPIHadoopFile, sometimes it throws "Delegation Token can be
> issued only with kerberos or web authentication"
