Vijay Srinivasaraghavan updated AMBARI-13300:
---------------------------------------------
Description:
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 though configuration recommendation is making use of it.
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
