Shantanu Deshmukh commented on KAFKA-4493: ------------------------------------------ We are using Kafka 0.10.1.0 and our Kafka producers are consuming huge amount of memory. Heapdump analysis showed almost 1 GB memory consumed by *org.apache.kafka.common.network.Selector* and *org.apache.kafka.common.network.KafkaChannel*. Can I apply this patch for Kafka 0.10.1.0? Sorry, but I don't know much about GIT and patching process. Please guide. > Connections to Kafka brokers should be validated > ------------------------------------------------ > > Key: KAFKA-4493 > URL: https://issues.apache.org/jira/browse/KAFKA-4493 > Project: Kafka > Issue Type: Improvement > Components: clients > Reporter: Ismael Juma > Priority: Major > > There have been a few reports of Kafka clients throwing an OOM because they > read 4 bytes from the stream and then use that to allocate a ByteBuffer > without validating that they are using the right security protocol or even > communicating with a Kafka broker. > It would be good to perform some validation in order to show a useful error > message to the user instead of the OOM. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
