独立运行 Apache Atlas

Question

我正在尝试在 Ubuntu 上以独立方式运行 Apache Atlas——这意味着无需设置 Solr 和/或 HBase。 我所做的（根据文档：http://atlas.apache.org/0.8.1/InstallationSteps.html）是克隆 Git 存储库，使用嵌入的 HBase 和 dSolr 构建 maven 项目：

mvn clean package -Pdist,embedded-hbase-solr

解压后的 tar.gz 文件并执行 bin/atlas_start.py - 没有更改任何配置。据我了解应该与 Atlas 一起实际启动 HBase 的文档 - 对吧？

这就是我在 logs/applocation.log 中找到的内容：

在我看来，脚本没有启动任何 HBase（和 Zookeeper）。

我错过了什么吗？

感谢您的提示！

Answer 1

好的，同时我发现了这个问题。启动脚本显然不执行设置一些环境变量的脚本 conf/atlas-env.sh。其中包括 MANAGE_LOCAL_HBASE 和 MANAGE_LOCAL_SOLR。因此，如果您将这两个环境变量设置为 true（并正确设置嵌入式 HBase 所需的 JAVA_HOME），那么 Atlas 会自动启动 HBase 和 Solr - 我们会得到一个本地运行的 Atlas 实例！

也许这可以帮助将来遇到同样问题的人！

Answer 2

2021 年 3 月更新

apache atlas有两种运行方式：

A) 从头开始​​构建它：

1. git 克隆https://github.com/apache/atlas
2. mvn clean install -DskipTests
3. mvn clean package -Pdist -DskipTests
4. 运行atlas_start.py:

   python <atlas-directory>/conf/atlas_start.py
   

B) 使用docker image:

docker-compose.yml

version: "3.3"

services:
  atlas:
    image: sburn/apache-atlas
    container_name: atlas
    ports:
      - "21000:21000"
    volumes:
      - "./bash_script:/app"
    command: bash -exc "/opt/apache-atlas-2.1.0/bin/atlas_start.py"

docker-compose up
