-----------------------------------
Summary: Mirror Maker2 Pod CrashLoopbackOff
Key: KAFKA-17784
URL: https://issues.apache.org/jira/browse/KAFKA-17784
Project: Kafka
Issue Type: Bug
Components: mirrormaker
Affects Versions: 3.7.1
Reporter: George Yang
Attachments: connect-1.log
When I use k8s deployment with mirrormaker v3.7.1, and deploy one kafka node in
each data center, I always got the crashloopbackoff error, please see the
attachment.
The configuration of mirrormaker is:
```configuration
# specify any number of cluster aliases
clusters = idca, idcb
# connection information for each cluster
# This is a comma separated host:port pairs for each cluster
# for e.g. "A_host1:9092, A_host2:9092, A_host3:9092"
idca.bootstrap.servers = 192.168.2.146:13399
idcb.bootstrap.servers = 192.168.2.147:13399
# enable and configure individual replication flows
idca->idcb.enabled = true
# regex which defines which topics gets replicated.
idca->idcb.topics = .*
idcb->idca.enabled = true
idcb->idca.topics = .*
