Kafka Getting error No resolvable bootstrap urls given in bootstrap servers
提问by Vimal Dhaduk
I'm pretty sure the bootstrap.servers is correct. Is there anything confliction in Maven or what wrong with Kafka??
我很确定 bootstrap.servers 是正确的。Maven 中是否有任何冲突或 Kafka 有什么问题？？
Before that It was working successfully. I added some Maven or Spark then something went wrong..
在此之前它运行成功。我添加了一些 Maven 或 Spark，然后出了点问题..
Can anyone knows how to resolve it?

"metadata.broker.list" is deprecated and "bootstrap.servers" is used instead. Removing "metadata.broker.list" configuration from your code should resolve the problem. Please find more details at difference between bootstrap.servers and metadata.broker.list
“metadata.broker.list”已弃用，而使用“bootstrap.servers”。从您的代码中删除“metadata.broker.list”配置应该可以解决问题。请在 bootstrap.servers 和 metadata.broker.list 之间的区别中找到更多详细信息

For anyone encountering this issue with MapR client libraries, you will get this if you forget the / on the front of the stream name.
对于在 MapR 客户端库中遇到此问题的任何人，如果您忘记了流名称前面的 /，您将得到此信息。
