独立运行Apache Atlas

提问于

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,使用嵌入式HBase和dSolr构建maven项目:

mvn clean package -Pdist,embedded-hbase-solr

解压缩resresh的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documentatino的理解 - 对吧?

这是我在logs / applocation.log中找到的:

对我而言,它看起来好像脚本没有启动HBase(和Zookeeper) .

我错过了什么吗?

谢谢你的提示!

    好的,同时我找到了问题 . 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!
