Mich:
When you execute the statements in Spark shell, you would see the types of
the intermediate results.
scala> val errlog = sc.textFile("/home/john/s.out")
errlog: org.apache.spark.rdd.RDD[String] = /home/john/s.out
MapPartitionsRDD[1] at textFile at <console>:24
scala> val sed = errlog.filter(line => line.contains("sed"))
sed: org.apache.spark.rdd.RDD[String] = MapPartitionsRDD[2] at filter at
<console>:26
scala> sed.collect()
res0: Array[String] = Array([WARNING] Unrecognised ...
Cheers
