Novice spark RDD word count, inquire!-CodePudding

HashMap Map1=new HashMap<> (a);
Map1. Put (1100);
Map1. Put (2150);
Map1. Put (3120);
HashMap Map2=new HashMap<> (a);
Map2. Put (2200);
Map2. Put (7, 20);
Map2. Put (3,66);
//may still has a lot of the map, and the key value is likely to be repeated, I put the map in the list
List Mylist
Then I use sparkcontext parallelize method how to word count?
