想用debezium+connect（distribute）把mysql的binlog传入kafka集群，可是一直不成功，curl无法将配置信息传给connect

环境：

1、kafka用的是confluent最新版本5.0.0，对应kafka应该是2.0.0版本
2、debezium也是最新debezium-connector-mysql-0.8.1.Final-plugin.tar.gz
3、jdk是1.8.0

操作步骤：

1、将zookeeper、kafka都安装好，并把debezium的jar包放在插件目录(share/java)中，以防万一还特别配置了环境路径
2、schema-registry.properties和connect-avro-distributed.properties配置参数基本都是默认，locaohost已改成本地地址。
3、依次启动 zk、kafka、schema-registry都没问题，brober顺利加入zk中注册的集群。
4、用/bin/connect-distributed -daemon ./etc/schema-registry/connect-avro-distributed.properties启动connect-distributed也没问题。
5、但是用curl给connect传配置参数问题就来了，curl传输信息如下：

curl 'https://84.10.100.13:8083/connectors' -X POST -i -H "Content-Type: application/json" -d '{ 
"name":"kafka-mysql", 
"config":{ 
"connector.clas":"io.debezium.connector.mysql.MySqlConnector", 
"database.hostname":"84.10.100.4", 
"database.port":"3306", 
"database.user":"learn", 
"database.password":"123456", 
"database.server.id":"2", 
"database.server.name":"mysql_4", 
"table.whitelist":"learn.students,learn.tb_emp4", 
"database.history.kafka.bootstrap.servers":"84.10.100.13:9092", 
"database.history.kafka.topic":"mysql_42.history", 
"include.schema.changes":"true", 
"mode":"incrementing", 
"database.history.skip.unparseable.ddl":"true" 
"snapshot.mode":"schema_only_recovery", 
"incrementing.column.name":"id", 
},"tasks":[],"type":null}'

然后就报错了：

HTTP/1.1 500 Internal Server Error

Content-Length: 476

麻烦大神看看该怎么解决，这个问题已经困扰很久了~多谢！
ps：rest api是不是也要启？但貌似启不起来。。。。。
