Description

hi
I want to run a MirrorSourceConnector with connect-distributed .
the connector config like this :
```
{
"name" : "cosmo-source",
"config" :

{ "connector.class" : "org.apache.kafka.connect.mirror.MirrorSourceConnector", "source.cluster.alias" : "cosmo", "target.cluster.alias" : "nana", "source.cluster.bootstrap.servers" : "192.168.4.42:9092,192.168.4.42:9093,192.168.4.42:9094", "topics" : ".*" }

}
```

when I post the rest requestion, it returns to me
```
{"name":"cosmo-source","config":

{"connector.class":"org.apache.kafka.connect.mirror.MirrorSourceConnector","target.cluster.alias":"nana","topics":".*","source.cluster.alias":"cosmo","name":"cosmo-source","source.cluster.bootstrap.servers":"192.168.4.42:9092,192.168.4.42:9093,192.168.4.42:9094"}

,"tasks":[],"type":"source"}
```
the task array is empty.

It's obvious that something's wrong here.

in connectDistributed.out
```
org.apache.kafka.common.config.ConfigException: Missing required configuration "bootstrap.servers" which has no default value.
```

full logs in the attachment.

thanks for any help.
