weijie.tong updated DRILL-7206:
-------------------------------
This issue is try to tune the HashJoin implementation codes. At right or full
join type , the HashJoinProbe will create a List<Integer> member to record the
unmatched composed indexes. It can be replaced by a primitive IntArrayList
without box/unbox operation ,also benefits the GC if there's more unmatched
items.
