Bui Thanh MInh updated KAFKA-12719:
-----------------------------------
Description:
Config:
```
clusters = DC1, DC2
NPS.bootstrap.servers = <DC1-Brokers>
NTL.bootstrap.servers = <DC2-Brokers>
# Source and target clusters configurations.
config.storage.replication.factor = 3
offset.storage.replication.factor = 3
status.storage.replication.factor = 3
DC1->DC2.enabled = true
DC2->DC1.enabled = true
# Mirror maker configurations.
offset-syncs.topic.replication.factor = 3
heartbeats.topic.replication.factor = 3
checkpoints.topic.replication.factor = 3
topics = .*
groups = .*
```
In my test case, I turn off whole DC1, and client will switch to DC2, after
that I bring cluster in DC1 back, restart MM2 with no error and realize that no
topics was replicated from DC2->DC1. I don't know why and how to check in this
case. What's wrong in my configuration?
