### Motivation We have 3 bookies in the same rack, and configured `E = 2, W = 2, A = 2`. When one bookie restarted, we found the ledger select bookie from the same rack failed in the ensemble change replacing the failed bookie step. Due to there being no log information in `selectRandomFromRack`, it's hard to debug the root cause. https://github.com/apache/bookkeeper/blob/02e64a4b97e03afc9993ab227f82a5956965c03f/bookkeeper-server/src/main/java/org/apache/bookkeeper/client/RackawareEnsemblePlacementPolicyImpl.java#L630-L679 ### Modification Add one warn log in `selectRandomFromRack` when selecting a new bookie node failed. -- This is an automated message from the Apache Git Service.
