Hi, I'm using local mode and read a text file as RDD using JavaSparkContext.textFile() API.
And then call "cache()" method on the result RDD. I look at the Storage information and find the RDD has 3 partitions but 2 of them have been cached. Is this a normal behavior? I assume all of partitions should be cached or none of them. If I'm wrong, what are the cases when number of "cached" partitions is less than the total number of partitions?
