[jira] [Updated] (KAFKA-12719) Kafka MirrorMaker 2 can only mirror in one direction in Active/Active config

     [ https://issues.apache.org/jira/browse/KAFKA-12719?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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?
