Hi [~ryannedolan]
We are trying to set up MM2 with connection distributed setup.
Worker configs are as follows
```
bootstrap.servers=abc-broker:9093
security.protocol=SASL_SSL
sasl.mechanism=PLAIN
sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule
required username="superuser" password="superuser_password";
group.id=connect-tails
key.converter=org.apache.kafka.connect.json.JsonConverter
value.converter=org.apache.kafka.connect.json.JsonConverter
key.converter.schemas.enable=false
value.converter.schemas.enable=false
internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false
offset.storage.topic=connect-offsets-test
config.storage.topic=connect-configs-test
status.storage.topic=connect-status-test
offset.flush.interval.ms=300000
producer.buffer.memory=1234
producer.ssl.truststore.password=truststore_password
producer.ssl.truststore.location=/opt/projects/confluent/wildcard.kafka.iggroup.local.jks
producer.ssl.keystore.password=keystore_password
producer.ssl.keystore.location=/opt/projects/confluent/wildcard.kafka.iggroup.local.jks
```
When i run below command, I can see worker connector created:
```nohup sh connect-distributed ../etc/kafka/connect-distributed-1.properties
&```
When I try to create a connector using POST call, I start seeing message as
```WARN [Producer clientId=connector-producer-MM9-0] Bootstrap broker
abc-broker:9093 (id: -1 rack: null) disconnected
(org.apache.kafka.clients.NetworkClient:1037)```
json content for POST call is as below
```

"target.cluster.ssl.keystore.location" :
"/opt/projects/confluent/ssl/wildcard.kafka.iggroup.local.jks" }
}
```
Note the bootstrap-server added in connect-distributed.properties file and the
target cluster bootstrap-server are same(abc-broker).
I have added all the SASL credentials, did a swap of source and destination
cluster in the json but I continue to get this broker disconnected WARNING.
We are on kafka version 0.11.0.3.
What is it that we are missing?
