### What changes were proposed in this pull request? This PR aims to upgrade Kafka client to 2.8.0. Note that Kafka 2.8.0 uses ZSTD JNI 1.4.9-1 like Apache Spark 3.2.0. ### Why are the changes needed? This will bring the latest client-side improvement and bug fixes like the following examples. - KAFKA-10631 ProducerFencedException is not Handled on Offest Commit - KAFKA-10134 High CPU issue during rebalance in Kafka consumer after upgrading to 2.5 - KAFKA-12193 Re-resolve IPs when a client is disconnected - KAFKA-10090 Misleading warnings: The configuration was supplied but isn't a known config - KAFKA-9263 The new hw is added to incorrect log when ReplicaAlterLogDirsThread is replacing log - KAFKA-10607 Ensure the error counts contains the NONE - KAFKA-10458 Need a way to update quota for TokenBucket registered with Sensor - KAFKA-10503 MockProducer doesn't throw ClassCastException when no partition for topic **RELEASE NOTE** - https://downloads.apache.org/kafka/2.8.0/RELEASE_NOTES.html - https://downloads.apache.org/kafka/2.7.0/RELEASE_NOTES.html ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Pass the CIs with the existing tests because this is a dependency change. Closes #32325 from dongjoon-hyun/SPARK-33913.

Apache Spark
Spark is a unified analytics engine for large-scale data processing. It provides high-level APIs in Scala, Java, Python, and R, and an optimized engine that supports general computation graphs for data analysis. It also supports a rich set of higher-level tools including Spark SQL for SQL and DataFrames, MLlib for machine learning, GraphX for graph processing, and Structured Streaming for stream processing.
Online Documentation
You can find the latest Spark documentation, including a programming guide, on the project web page. This README file only contains basic setup instructions.
Building Spark
Spark is built using Apache Maven. To build Spark and its example programs, run:
./build/mvn -DskipTests clean package
(You do not need to do this if you downloaded a pre-built package.)
More detailed documentation is available from the project site, at "Building Spark".
For general development tips, including info on developing Spark using an IDE, see "Useful Developer Tools".
Interactive Scala Shell
The easiest way to start using Spark is through the Scala shell:
./bin/spark-shell
Try the following command, which should return 1,000,000,000:
scala> spark.range(1000 * 1000 * 1000).count()
Interactive Python Shell
Alternatively, if you prefer Python, you can use the Python shell:
./bin/pyspark
And run the following command, which should also return 1,000,000,000:
>>> spark.range(1000 * 1000 * 1000).count()
Example Programs
Spark also comes with several sample programs in the examples
directory.
To run one of them, use ./bin/run-example <class> [params]
. For example:
./bin/run-example SparkPi
will run the Pi example locally.
You can set the MASTER environment variable when running examples to submit
examples to a cluster. This can be a mesos:// or spark:// URL,
"yarn" to run on YARN, and "local" to run
locally with one thread, or "local[N]" to run locally with N threads. You
can also use an abbreviated class name if the class is in the examples
package. For instance:
MASTER=spark://host:7077 ./bin/run-example SparkPi
Many of the example programs print usage help if no params are given.
Running Tests
Testing first requires building Spark. Once Spark is built, tests can be run using:
./dev/run-tests
Please see the guidance on how to run tests for a module, or individual tests.
There is also a Kubernetes integration test, see resource-managers/kubernetes/integration-tests/README.md
A Note About Hadoop Versions
Spark uses the Hadoop core library to talk to HDFS and other Hadoop-supported storage systems. Because the protocols have changed in different versions of Hadoop, you must build Spark against the same version that your cluster runs.
Please refer to the build documentation at "Specifying the Hadoop Version and Enabling YARN" for detailed guidance on building for a particular distribution of Hadoop, including building for particular Hive and Hive Thriftserver distributions.
Configuration
Please refer to the Configuration Guide in the online documentation for an overview on how to configure Spark.
