Question

我正在为EKS上的Hyperledger Fabric建立新集群。群集具有4个kafka节点，3个zookeeper节点，4个对等方，3个订购者，1个CA。所有容器都单独放置，并且kafka / zookeeper后端也很稳定。我可以通过SSH进入任何kafka / zookeeper，并检查与其他任何节点的连接，创建主题，发布消息等。kafka可从所有订购者通过Telnet访问。

当我尝试创建频道时，我从订购器中收到以下错误：

2019-04-25 13:34:17.660 UTC [orderer.common.broadcast] ProcessMessage -> WARN 025 [channel: channel1] Rejecting broadcast of message from 192.168.94.15:53598 with SERVICE_UNAVAILABLE: rejected by Consenter: backing Kafka cluster has not completed booting; try again later

Kafka领导者报告以下错误：

Answer 1

该错误表明您收到的消息大于允许的最大大小，默认大小为〜100MB。尝试增加server.properties文件中的以下属性，以便它可以容纳较大的接收（在这种情况下，至少为369295617字节）：

# Set to 500MB
socket.request.max.bytes=500000000

，然后重新启动Kafka群集。

如果这对您不起作用，那么我猜您正在尝试连接到非SSL侦听器。因此，您必须验证代理的SSL侦听器端口为9092（或相应的端口，以防您未使用默认端口）。以下应该可以解决问题：

listeners=SSL://:9092
advertised.listeners=SSL://:9092
inter.broker.listener.name=SSL

Kafka通过Hyperledger Fabric Orderer连接提供无效的接收大小
