application container. Karaf can be used as a standalone container, supporting a wide range of applications and technologies. It also supports the "run anywhere" concept (on any machine with Java, cloud one file. • Provisioning: Apache Karaf supports a large set of URLs where you can install your applications (Maven repository, HTTP, file, etc). It also provides the concept of "Karaf Features" which is bin\karaf.bat server bin/start bin\start.bat Clean start Apache Karaf stores all previously applications installed and changes that you did in the data folder. If you want to start from a clean state

metadata requests and receive metadata results. – It enables easy submission of self-contained applications for batch processing, such as Spark jobs. • MySQL Protocol – A MySQL-compatible interface that computing resources. Besides, Kyuubi also supports submissions of code snippets and self-contained applications serverlessly for more ad- vanced usage. 2.1 Ease of Use End users could have an optimized experience execution environments. Here we use Spark for demonstration. These essential components are JVM-based applications. So, the JRE needs to be pre-installed and the JAVA_HOME is correctly set to each component.
