[SPARK-2412] CoalescedRDD throws exception with certain pref locs
If the first pass of CoalescedRDD does not find the target number of
locations AND the second pass finds new locations, an exception is thrown, as
"groupHash.get(nxt_replica).get" is not valid.
The fix is just to add an ArrayBuffer to groupHash for that replica if it
didn't already exist.
