Hi All, There is some file with line number N + M,, as I need to read the first N lines into one RDD . 1. i) read all the N + M lines as one RDD, ii) select the RDD's top N rows, may be some one solution;2. if introduced some broadcast variable set N, then it is used to decide while map the file RDD. Only map its first N rows, this may notwork, however. Is there some better solution? Thank you,Zhiliang
