Bug Report

What did you do?

  • The cluster has hot read flow and generates move-hot-read-peer scheduling.

What did you expect to see?

  • A(L) B(F) C(F) -> B(F) C(F) D(L). Hot reading Leader successfully moved to the new Store-D from Store-A.

What did you see instead?

  • Due to the use of CreateMovePeerOperator to generate the schedule. By default, the new Leader will be B or C, not D.

What version of PD are you using (pd-server -V)?

Release Version: v5.0.1
