If java is successfully installed on your machine, you could see the version of the installed Java. If Java is not downloaded, please download the latest version of JDK by visiting the following link and download latest version. Please download the file on your machine. Generally, files being downloaded are stored in the downloads folder, verify it and extract the tar setup using the following commands.
Step 1. To install ZooKeeper framework on your machine, visit the following link and download the latest version of ZooKeeper. Create a file with name Dockerfile. Dockerfile contains instructions to prepare Docker image with our Java Application. Login as root user. Navigate into java-application directory and run the following command. Instructions in the Dockerfile are executed. Please observe that there is dot.
Docker image is successfully built. Run the following command to run the java-application Docker image in a container. Save the Docker Image file to a tar file, so that the image file could be copied to other machines through disk storage devices like pen-drive, etc.
In this Docker Tutorial — Docker Java Example, we have learnt to build a Docker Image with Java Application and also how to save the image to a file and transfer it to other computers or servers. Create a directory A separate directory is useful to organise docker applications.
We shall use the name java-application 2. Dockerfile Create a file with name Dockerfile. Following is the content of Dockerfile.
Verify contents of java-application directory 5. This only matters if you are using Scala and you want a version built for the same Scala version you use. Otherwise any version should work 2. Here is a summary of some notable changes: The deprecation of support for Java 8 and Scala 2. Here is a summary of some notable changes: TLSv1. Here is a summary of some notable changes: TLS 1. Here is a summary of some notable changes: Allow consumers to fetch from closest replica.
Support for incremental cooperative rebalancing to the consumer rebalance protocol. MirrorMaker 2. New Java authorizer Interface. Support for non-key joining in KTable. Administrative API for replica reassignment. Kafka Connect now supports incremental cooperative rebalancing. Kafka Streams now supports an in-memory session store and window store.
The AdminClient now allows users to determine what operations they are authorized to perform on topics. There is a new broker start time metric. We now track partitions which are under their min ISR count. Consumers can now opt-out of automatic topic creation, even when it is enabled on the broker.
Kafka components can now use external configuration stores KIP 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.
