经纪人重启后卡夫卡重新连接

Question

我正在使用kafka生成器插件进行logback，并且在重新启动代理之后，我连接到它的所有JVM都获得了大量例外：

11:22:48.738 [kafka-producer-network-thread | app-logback-relaxed] cid: clid: E [        @] a: o.a.k.c.p.internals.Sender - [Producer clientId=id-id-logback-relaxed] Uncaught error in kafka producer I/O thread:  ex:java.lang.NullPointerException: null

不管kafka再次上升，只重新启动JVM帮助

可以以某种方式设置它会自动重新连接吗？
