以下是我使用的版本.
// kafka
"org.apache.kafka" %% "kafka" % "1.0.0"
"net.manub" %% "scalatest-embedded-kafka" % "0.14.0" % Test
//flink
"org.apache.flink" %% "flink-scala" % "1.4.2"
"org.apache.flink" %% "flink-streaming-scala" % "1.4.2"
"org.apache.flink" %% "flink-connector-kafka-0.9" % "1.4.0"
"org.apache.flink" %% "flink-connector-cassandra" % "1.4.2"
推荐答案
我遇到了同样的问题.当消费者运行另一台计算机而不是 kafka 服务器时，就会发生这种情况.请修改
config/server.properties .listeners=PLAINTEXT://serverip:9092.
I met same problem. when consumer run another computer,not kafka server,this will happen. pls modify
config/server.properties . listeners=PLAINTEXT://serverip:9092.
注意:severip 不能设置为 127.0.0.1 或 localhost，应设置为消费者可以连接的 ip.
ATTENTION:severip could not set to 127.0.0.1 or localhost, should be set to the ip that consumer can connect to.
