我正在使用合流平台进行试验。我正在使用启动所有服务。 confluent local start 我得到以下输出

zookeeper is [UP]
Starting kafka
kafka is [UP]
Starting schema-registry
schema-registry is [UP]
Starting kafka-rest
kafka-rest is [UP]
Starting connect
-Kafka Connect failed to start
connect is [DOWN]

我确实清理了一下，又用了一次
confluent local destroy confluent local log connect f 显示以下错误

Caused by: org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment.

我检查了所有端口并验证了它们是否可用。不知道从这里到哪里去。
谢谢
