Anoop Sam John commented on HBASE-17232:
----------------------------------------
Looks ok.
We are sure we wont be adding duplicated scanners in any case.. The Set might
have been selected to make sure no dup addition.. But I believe there is no dup
chance at all. +1 if QA is fine. Tks.
> Replace HashSet with ArrayList
