Custom records reader PST file format in Spark Scala
问题 I am working on PST files, I have worked on writing custom record reader for a Mapreduce program for different input formats but this time it is going to be spark. I am not getting any clue or documentation on implementing record readers in spark. Can some body help on this? Is it possible to implement this functionality in spark? 来源： https://stackoverflow.com/questions/52272887/custom-records-reader-pst-file-format-in-spark-scala
