Hi, I start to learn Kafka and.. I have first problem. I started Zookeeper, I started Kafka - both on localhost. Seems all is fine. But when I try to execute command:
zookeeper-shell.bat localhost:2181 ls /brokers/ids I get error: Connecting to localhost:2181 WATCHER:: WatchedEvent state:SyncConnected type:None path:null [0] [2022-07-30 19:54:22,524] ERROR Exiting JVM with code 0 (org.apache.zookeeper.util.ServiceUtils) And in Zookeeper: [2022-07-30 19:54:53,335] INFO Expiring session 0x10000190aa20001, timeout of 30000ms exceeded (org.apache.zookeeper.server.ZooKeeperServer) [2022-07-30 19:58:05,393] WARN Close of session 0x10000190aa20002 (org.apache.zookeeper.server.NIOServerCnxn) java.io.IOException: An existing connection was forcibly closed by the remote host at java.base/sun.nio.ch.SocketDispatcher.read0(Native Method) at java.base/sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:43) at java.base/sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:276) at java.base/sun.nio.ch.IOUtil.read(IOUtil.java:245) at java.base/sun.nio.ch.IOUtil.read(IOUtil.java:223) at java.base/sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:358) at org.apache.zookeeper.server.NIOServerCnxn.doIO(NIOServerCnxn.java:324) at org.apache.zookeeper.server.NIOServerCnxnFactory$IOWorkRequest.doWork(NIOServerCnxnFactory.java:522) at org.apache.zookeeper.server.WorkerService$ScheduledWorkRequest.run(WorkerService.java:154) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834) server.properties: listeners=PLAINTEXT://localhost:9092 advertised.listeners=PLAINTEXT://localhost:9092 zookeeper.connection.timeout.ms=18000 zookeeper.properties: clientPort=2181 maxSessionTimeout=18000 What can be the reason?
