Subject [jira] [Created] (AMBARI-13300) Enhance Stack Advisor to support Blueprint recommendation
Date Fri, 02 Oct 2015 20:07:26 GMT
Vijay Srinivasaraghavan created AMBARI-13300:
------------------------------------------------

             Summary: Enhance Stack Advisor to support Blueprint recommendation
                 Key: AMBARI-13300
                 URL: https://issues.apache.org/jira/browse/AMBARI-13300
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server, blueprints
            Reporter: Vijay Srinivasaraghavan


StackAdvisor component as of now can recommend and validate component layout and configurations.
Precisely, we can
request StackAdvisor API for any of these recommendations (host_groups, configurations, configuration-dependencies).

Though StackAdvisor has got the host specific resouce details (memory, cpu, disks, os type,
etc.,) it does not use these details while recommending the host-component mapping. 

Applications/Service Providers that are using Amabri Rest API/Blueprints to provision and
manage Hadoop clusters will largely benefit if Stack Advisor component is enhanced to address
following GAPs

- Support for Heterogenous hosts (Master, Slaves, Clients)

- Provide both host group and configuration recommendations in same blueprint output response
instead of requesting one at
a time (as of now we can request one of the following - host_groups, configurations, configuration-dependencies
not a combination/al of them)

-Provide HA blueprint recommendation in stack advisor (creating handcrafted blueprint without
using StackAdvisor limits
the potential of StackAdvisor component)

- Recommend appropriate hosts to services based on the host resource availability and service
resource requirements
