… and forth (apache#39333) BUG: partition rebalancer migrates tablets back and forth: move from A to B, then B to A, then A to B, ... . The reason is the counting tablet num of backends is incorrect. It doesn't considering the pending and running sched tasks. After these tasks finished, the tablet num will change. Fix: when calcuting the tablet num of backend, it should consider the in-progress moves which will change tablet num later.
