运行 Apache Atlas 独立版

Question

我正在尝试运行 Apache Atlas 在 Ubuntu 上以独立的方式运行 - 这意味着无需设置 Solr and/or 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

解压结果 tar.gz 文件并执行 bin/atlas_start.py - 没有更改任何配置。根据我对应该实际启动 HBase 和 Atlas 的文档的理解 - 对吗？

这是我在 logs/applocation.log:

对我来说，脚本似乎没有启动 HBase（和 Zookeeper）。

我是不是漏掉了什么？

感谢您的提示！

Answer 1

好的，同时我想通了这个问题。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 Atlas 实例！

也许这对以后遇到同样问题的人有帮助！

Answer 2

运行apache图集有两种方式：

A) 从头开始构建：

git 克隆 https://github.com/apache/atlas
mvn clean install -DskipTests
mvn clean package -Pdist -DskipTests

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
