Question

我试图在Ubuntu上以独立的方式运行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）克隆了Git存储库，用嵌入式HBase和dSolr构建了maven项目：

解压缩resuting tar.gz文件并执行bin / atlas_start.py - 未更改任何配置。据我所知，应该实际启动HBase和Atlas的documentatino - 对吧？

这是我在logs / applocation.log中找到的：

对我来说，它看起来就好像脚本没有启动HBase（和Zookeeper）。

我错过了什么吗？

感谢您的提示！

Answer 1

好的，同时我找出了问题。启动脚本显然不执行脚本conf / atlas-env.sh，它设置了一些环境变量。其中包括MANAGE_LOCAL_HBASE和MANAGE_LOCAL_SOLR。因此，如果您将这两个env变量设置为true（并且正确设置嵌入式HBase所需的JAVA_HOME），那么Atlas会自动启动HBase和Solr - 我们将获得一个本地运行的Atlas实例！

也许这可以帮助将来遇到同样问题的人！

apache atlas有两种运行方式：

A) 从头开始构建：

git clone 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

独立运行Apache Atlas
