… candidate speed (apache#36509) When partition reblancer choose candidate tablets, it will call tabletListOfA.removeAll(tabletListOfB), but list.removeAll(list)'s runtime is O(n^2). Then if each BE contains 10w+ tablets, it's rather slow. And we found a online case the tablet scheduler thread is busy at it. So need improve this search.
