Subject [jira] [Created] (AMBARI-11866) Blueprints processor should enable command retry by default
Date Thu, 11 Jun 2015 20:09:00 GMT
Robert Nettleton created AMBARI-11866:
-----------------------------------------

             Summary: Blueprints processor should enable command retry by default
                 Key: AMBARI-11866
                 URL: https://issues.apache.org/jira/browse/AMBARI-11866
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: Robert Nettleton
            Assignee: Robert Nettleton
            Priority: Critical
             Fix For: 2.1.0


The new provisioning model used by Blueprints installs and starts services using much more
parallelization.  This means that some ordering issues not handled by individual components
can occur, keeping some services from starting properly initially.  

The new command retry feature enabled in Ambari can be used to request that installs and commands
be retried in the event of a failure.  

The details of the new retry feature can be found in AMBARI-11804. 

The Blueprint processor should enable this feature by default for Cluster deployments based
on Blueprints.  While providing valid defaults, the user should also be able to override these
defaults in the "cluster-env" configuration section of either the Blueprint or Cluster Creation
Template. 

I'm working on a fix for this, and will be submitting a patch shortly.
