livy-repl-jars配置项

`livy-repl-jars` 是 Livy（一个开源的交互式大数据分析工具）中的一个配置项，用于指定需要在 Livy 会话中使用的 REPL JAR 包。REPL（Read-Eval-Print Loop）是一种交互式编程环境，用于快速测试和验证代码。在 Livy 中，可以使用 `livy-repl-jars` 指定需要在会话中使用的 REPL JAR 包。

`livy-repl-jars` 的值应该是一个 JAR 包列表，以逗号分隔。这些 JAR 包应该在 Livy 运行时的 CLASSPATH 中可用。可以使用 `livy.file.local-dir-whitelist` 配置项指定 Livy 可以从哪些目录中加载 JAR 包。例如，以下是一个 `livy.conf` 文件中的 `livy-repl-jars` 配置项：

livy.repl.jars = /path/to/my/repl.jar,/path/to/my/other/repl.jar

这将指定 Livy 在会话中使用 `/path/to/my/repl.jar` 和 `/path/to/my/other/repl.jar` 这两个 JAR 包。

Apache Livy

Apache Livy is an open-source project that provides a REST interface for interacting with Apache Spark clusters. It allows users to submit and manage Spark jobs from remote applications, such as web or mobile apps, without the need for direct access to the Spark cluster.

Livy provides a simple REST API for submitting jobs, monitoring job status, and retrieving job results. It also supports various programming languages, including Java, Scala, and Python. Additionally, Livy supports different authentication mechanisms, such as OAuth2 and Kerberos, to ensure secure access to the Spark cluster.

Livy is designed to simplify the deployment and management of Spark applications in a distributed environment. It enables users to run Spark jobs on a shared cluster, reducing the need for individual Spark deployments. Moreover, Livy allows users to leverage the scalability and performance benefits of Spark without having to manage the underlying infrastructure.

Overall, Apache Livy is a valuable tool for organizations looking to streamline their Spark deployment and management processes. It provides a simple, secure, and scalable way to interact with Spark clusters, making it easier for users to develop and deploy Spark applications.
