Hello  
Is this during Kafka start or Kafka Mirror Maker start?
What if you try to pass the values in 
"Kafka Broker Advanced Configuration Snippet (Safety Valve) for ssl.properties" to pass the properties (ssl.keystore.password, ssl.key.password and ssl.truststore.password. i.e, without .generator)?
Kafka MirrorMaker has a known issue: .generator properties do not work for producer configs.
This affects CDK 3.X (CDH 6.X contains a fix for this issue from 6.2). - CDH-73094 
 
Which version are you using? Please specify both CM and CDH version. 

This can cause issue too if they are not compatible. 

Is this an upgrade cluster or new?
