Hi all, In fact this is a question regarding Zookeeper but very related to Kafka. I'm doing a test in order to check that we can create up to 100k topics in a kafka cluster, so we can manage multitenancy this way.
After a proper setup, I have managed to create those 100k topics in Kafka, but now I find that I can't retrieve the list of topics using kafka-topics.sh, this is the error I get: [2017-08-07 08:12:37,085] WARN Session 0x15dbb9894d00003 for server ..., unexpected error, closing socket connection and attempting reconnect (org.apache.zookeeper.ClientCnxn) java.io.IOException: Packet len4194320 is out of range! at org.apache.zookeeper.ClientCnxnSocket.readLength(ClientCnxnSocket.java:112) at org.apache.zookeeper.ClientCnxnSocketNIO.doIO(ClientCnxnSocketNIO.java:79) at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:366) at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1141) I have read that this is related to a property in Zookeeper named jute.maxbuffer, and that I have to set it up through a java property. But after some tries I'm not getting any result, so I would like to ask you if somebody has found this error, and how have you solved it. Thanks in advance, David
