In the AWS console, launch a new instance. + Select `Ubuntu` as the operating system and `t2.xlarge` as the instance type. + Create a key pair named *Gravitino.pem* for SSH access and download it. + Allow HTTP and HTTPS traffic if you want to connect to the instance remotely. + Set the Elastic Block Store storage to 20GiB. + Leave all other settings as their defaults. + Other operating systems and instance types may work, but are not be fully tested. + +1. Start the instance and connect to it via SSH using the downloaded `.pem` file: + + ```shell + ssh ubuntu@<IP_address> -i ~/Downloads/Gravitino.pem + ``` + + **Note**: you may need to adjust the permissions on your `.pem` file using + `chmod 400` to enable SSH connections. + +1. Update the Ubuntu OS to ensure it's up-to-date: + + ```shell + sudo apt update + sudo apt upgrade + ``` + + <!--TODO: need Red Hat commands?--> + You may need to reboot the instance for all changes to take effect. + +1.

Install the Java Development Kit (JDK), Java 8, 11 and 17 are supported. + This can be done using [sdkman](https://sdkman.io/), for example: + + ```shell + sdk install java <version> + ``` + + You can also use different package managers to install JDK, for example, + [Homebrew](https://brew.sh/) on macOS, `apt` on Ubuntu/Debian, and + `yum` on CentOS/RedHat. + +## Install Gravitino + +You can install Gravitino from the binary release packages or the container images. +Follow [how-to-install](../how-to-install.md). + +Or you can install Gravitino from scratch. +Follow [how-to-build](../how-to-build.md) and [how-to-install](../how-to-install.md). + +## Start Gravitino + +Start Gravitino using the `gravitino.sh` script: + +```shell +<path-to-gravitino>/bin/gravitino.sh start +``` + +## Install Apache Hive + +If you already have Apache Hive and Apache Hadoop in your environment, +you can skip this step and use the existing service with Gravitino. +Or else, you can follow the [instructions](./hive.md) to install Apache Hive. + +## Interact with Apache Gravitino API + +After having deployed the Gravitino server, you can interact it using +the RESTful APIs to create and modify metadata. + +:::tip +The following examples use `localhost` as the host name. +You may need to revise it accordingly based on the environment +you are using. +::: + +1. Create a Metalake: + + ```shell + curl -X POST -H "Accept: application/vnd.gravitino.v1+json" \ + -H "Content-Type: application/json" \ + -d '{"name":"my-metalake","comment":"Test metalake"}' \ + http://localhost:8090/api/metalakes + ``` + + Verify the MetaLake has been created: + + ```shell + curl -X GET -H "Accept: application/vnd.gravitino.v1+json" \ + -H "Content-Type: application/json" \ + http://localhost:8090/api/metalakes + + curl -X GET -H "Accept: application/vnd.gravitino.v1+json" \ + -H "Content-Type: application/json" \ + http://localhost:8090/api/metalakes/my-metalake + ``` + + Note that if you are requesting a Metalake that doesn't exist, you'll get a + `NoSuchMetalakeException` error. + + ```shell + curl -X GET -H "Accept: application/vnd.gravitino.v1+json" \ + -H "Content-Type: application/json" \ + http://localhost:8090/api/metalakes/none + ``` + +1. Create a catalog in Hive: + + First, list the current catalogs to verify that no catalogs exist. + + ```shell + curl -X GET -H "Accept: application/vnd.gravitino.v1+json" \ + -H "Content-Type: application/json" \ + http://localhost:8090/api/metalakes/my-metalake/catalogs + ``` + + Create a new Hive catalog. + + ```shell + curl -X POST -H "Accept: application/vnd.gravitino.v1+json" \ + -H "Content-Type: application/json" \ + -d '{"name":"my-catalog","comment":"Test catalog", "type":"RELATIONAL", "provider":"hive", "properties":{"metastore.uris":"thrift://localhost:9083"}}' \ + http://localhost:8090/api/metalakes/my-metalake/catalogs + ``` + + Verify that the catalog has been created: + + ```shell + curl -X GET -H "Accept: application/vnd.gravitino.v1+json" \ + -H "Content-Type: application/json" \ + http://localhost:8090/api/metalakes/my-metalake/catalogs + ``` + + :::tip + The `metastore.uris` property used for the Hive catalog has to + be adapted to your environment. + ::: + +## Next steps + +- Delve deeper into the [documentation](https://gravitino.apache.org/docs/latest) + for advanced features and configuration options. + +- Bookmark [Gravitino Website](https://gravitino.apache.org) for updates, + laest releases, new features, optimizations, and security enhancements. + +- Read our [blogs](https://gravitino.apache.org/blog) + +- Join the Gravitino community forums to connect with developers and other users, + for experience sharing and seeking helps if needed. + Questions and comments are all welcomed. + + - Join [Gravitino Slack channel](https://the-asf.slack.com) + - Explore the GitHub repository for [issues](https://github.com/apache/gravitino/issues) + or [pull requests](https://github.com/apache/gravitino/pulls), + and pick something you are interested to work on.
