?It is pretty much encoded in the stack advisor logic. Its not translated to a document as
such. It also evolves based on feedback received.


You can go through the stack advisor code to get some idea. A good way is to deploy a 3/5/7
node cluster and export the blueprint. That can pretty much be used as a template.


There is an effort to integrate stack advisor with blueprint as well.

Thanks Sumit. But can you please explain the strategy employed by Ambari, so that in case
any tweaks are required, it would be helpful. For example, if the cluster is being setup by
using Blueprints, what should be the placement guidelines to be considered?

Regards
Vijay

Subject: Component placement strategy - Ambari

Hi,

Is there any recommendation on the components' placement across the cluster i.e. how the various
Hadoop services have to be distributed across the cluster? Especially around which services
need to be placed together and which two shouldn't be placed together?

For example, on the machine which acts as amber server, which other components can be installed?
Is there any such guideline available at the moment?

Thanks & Regards
Vijay
