独立运行Apache Atlas

Question

我试图在Ubuntu上以独立方式运行Apache Atlas，这意味着不必设置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，并使用HBase和dSolr嵌入构建Maven项目：

mvn clean package -Pdist,embedded-hbase-solr

解压缩重新开始的tar.gz文件并执行bin / atlas_start.py-无需更改任何配置。据我了解，实际上应该与Atlas一起启动HBase的documentatino-对吗？

这是我在logs / applocation.log中找到的：

在我看来，该脚本似乎没有启动HBase（和Zookeeper）。

我想念什么吗？

感谢您的提示！

Answer 1

好的，与此同时我找出了问题所在。显然，启动脚本不会执行conf / atlas-env.sh脚本，该脚本设置了一些环境变量。其中有MANAGE_LOCAL_HBASE和MANAGE_LOCAL_SOLR。因此，如果将这两个env vars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-我们将获得Atlas的本地运行实例！

也许这可以帮助将来遇到相同问题的人！
