[jira] [Updated] (AMBARI-7072) Metadata information exposed through
API
[ https://issues.apache.org/jira/browse/AMBARI-7072?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Krisztian Horvath updated AMBARI-7072:
--------------------------------------
Description:
We'd like to retrieve metadata information (most of them are already persisted) through the API. We have open sourced a project called Periscope https://github.com/sequenceiq/periscope which brings SLA policy based autoscaling for Hadoop clusters installed with Ambari, and when up and downscaling clusters we need to know certain metadata information listed below - these features we have implemented in Periscope but would like to add in Ambari API, REST client and shell:
1. Ability to know the host-hostgroup relationship - from both directions
2. Ability to know the services/components-host relationship - from both directions
3. Ability to know the blueprint-cluster(s) relationship
4. Once Slider is supported, keep and retrieve the Slider apps related metadata
