The easiest way to move forwards is to "reset" your environment and try restarting. This process will destroy any data you may have in existing topics. If you are using WIndows 10, and are having trouble starting ksqlDB, firstly try reset the Confluent platform using confluent local destroy as described above.
You can review the CP logs for a given service with the confluent log command. For example, to see the Zookeeper logs. This is due to a missing setting with the supplied ksql-server.
Sometimes you want a more powerful command line terminal manager - especially if you wish to "split" the window. Skip to content. Star 0. Permalink master. Branches Tags. Could not load branches. Could not load tags. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. How do you display multiple split terminals at the same time? Raw Blame. We have implemented improved replica fetcher behavior when errors are encountered.
Here is a summary of some notable changes: Java 11 support Support for Zstandard, which achieves compression comparable to gzip with higher compression and especially decompression speeds KIP Avoid expiring committed offsets for active consumer group KIP Provide Intuitive User Timeouts in The Producer KIP Kafka's replication protocol now supports improved fencing of zombies.
Previously, under certain rare conditions, if a broker became partitioned from Zookeeper but not the rest of the cluster, then the logs of replicated partitions could diverge and cause data loss in the worst case KIP Here is a summary of some notable changes: KIP adds support for prefixed ACLs, simplifying access control management in large secure deployments.
Bulk access to topics, consumer groups or transactional ids with a prefix can now be granted using a single rule. Access control for topic creation has also been improved to enable access to be granted to create specific topics or topics with a prefix.
Host name verification is now enabled by default for SSL connections to ensure that the default SSL configuration is not susceptible to man-in-the-middle attacks. You can disable this verification if required. You can now dynamically update SSL truststores without broker restart. With this new feature, you can store sensitive password configs in encrypted form in ZooKeeper rather than in cleartext in the broker properties file.
The replication protocol has been improved to avoid log divergence between leader and follower during fast leader failover. We have also improved resilience of brokers by reducing the memory footprint of message down-conversions.
By using message chunking, both memory usage and memory reference time have been reduced to avoid OutOfMemory errors in brokers. Kafka clients are now notified of throttling before any throttling is applied when quotas are enabled. This enables clients to distinguish between network errors and large throttle times when quotas are exceeded. We have added a configuration option for Kafka consumer to avoid indefinite blocking in the consumer. We have dropped support for Java 7 and removed the previously deprecated Scala producer and consumer.
Kafka Connect includes a number of improvements and features. KIP enables you to control how errors in connectors, transformations and converters are handled by enabling automatic retries and controlling the number of errors that are tolerated before the connector is stopped. More contextual information can be included in the logs to help diagnose problems and problematic messages consumed by sink connectors can be sent to a dead letter queue rather than forcing the connector to stop.
KIP adds a new extension point to move secrets out of connector configurations and integrate with any external key management system. The placeholders in connector configurations are only resolved before sending the configuration to the connector, ensuring that secrets are stored and managed securely in your preferred key management system and not exposed over the REST APIs or in log files.
Scala users can have less boilerplate in their code, notably regarding Serdes with new implicit Serdes. Message headers are now supported in the Kafka Streams Processor API, allowing users to add and manipulate headers read from the source topics and propagate them to the sink topics. Windowed aggregations performance in Kafka Streams has been largely improved sometimes by an order of magnitude thanks to the new single-key-fetch API.
We have further improved unit testibility of Kafka Streams with the kafka-streams-testutil artifact. Here is a summary of some notable changes: Kafka 1. ZooKeeper session expiration edge cases have also been fixed as part of this effort. Controller improvements also enable more partitions to be supported on a single cluster. KIP introduced incremental fetch requests, providing more efficient replication when the number of partitions is large. Some of the broker configuration options like SSL keystores can now be updated dynamically without restarting the broker.
See KIP for details and the full list of dynamic configs. Delegation token based authentication KIP has been added to Kafka brokers to support large number of clients without overloading Kerberos KDCs or other authentication servers.
Additionally, the default maximum heap size for Connect workers was increased to 2GB. Several improvements have been added to the Kafka Streams API, including reducing repartition topic partitions footprint, customizable error handling for produce failures and enhanced resilience to broker unavailability. See KIPs , , , and for details. Here is a summary of a few of them: Since its introduction in version 0. For more on streams, check out the Apache Kafka Streams documentation, including some helpful new tutorial videos.
These are too many to summarize without becoming tedious, but Connect metrics have been significantly improved KIP , a litany of new health check metrics are now exposed KIP , and we now have a global topic and partition count KIP

I want to use Kafka in my machine for a project. I extracted it to my C drive in a folder named as Kafka. I made the changes in zookeeper. This is all I am getting. Kindly guide me to fix it and help me to run kafka. I solved the problem and now it is working fine.
Then there is no error. Thanks to those who tried. Though the above steps help us in installing Kafka in Windows, there is an inherent defect in using Kafka with Windows. There is an error in the current Kafka for windows, which stops the Kafka server every time the log files are purged of the data.
