Ambari Blueprint : Sizing Components memory based on Host Environment

Jagatheeshr — Thu, 29 Oct 2015 23:53:51 GMT

I am working Chef blueprint deployment where in blueprint json memory values gets adjusted based on the system memory available. the target system system memory can be from 8 GB to 145GB.

HDP will be used for running OpenSOC.(Storm,Kafka,HBase,HDFS)

For Example Kafka,KAFKA Heap > 5GB would not give any benefit whatever the source memory is.

So looking for automic sizing of the componetns(Hbase,Storm,AMS,HDFS) where more memory would help the system to perform better .

This is for HDP 2.2.8 and Ambari 2.1.2.

@jramakrishnan@hortonworks.com - this is similar to the question you asked earlier. The current incarnation of blueprints is about faithfully replicating a known configuration into a new cluster. It was not intended to dynamically configure the new cluster based on its available resources.

But, as mentioned by @smohanty@hortonworks.com and @rnettleton@hortonworks.com, the next release of Ambari, Ambari-2.1.3, will incorporate an option to use Stack Advisor. That option will do some dynamic over-rides of the blueprint to tune and optimize the configuration for the target cluster.

Thanks @David Schorow. I am looking for some guidance on the current release. As we are doing it right now.

Ambari Blueprints does not (as of 2.1.2) use the StackAdvisor to provide recommended configurations. It is planned for Ambari 2.1.3 (AMBARI-13487).

But you can use the recommendation engine yourself.

The following script uses the Recommendation API (/api/v1/stacks/HDP/versions/<ver>/recommendations😞

https://github.com/seanorama/ambari-bootstrap/tree/master/deploy
The script generates & deploys a Blueprint, including StackAdvisor recommendations.
Alternatively use it to get the recommendations only (set 'export deploy=false' to just generate the configurations)
Or borrow the API calls to integrate into your own deployment method.

p.s. a few projects have borrowed this code to generate configurations throughout the life of a cluster.

p.s.s. these scripts are used by Google's bdutil so have been heavily field tested.

@jramakrishnan@hortonworks.com - I recall @jplayer@hortonworks.com @nfakhar@hortonworks.com adapted the code for diverse hardware on AWS.
