[jira] [Created] (AMBARI-11542) Occasional database deadlock detected when provisioning cluster via blueprint api

John Speidel created AMBARI-11542:
-------------------------------------

             Summary: Occasional database deadlock detected when provisioning cluster via blueprint api 
                 Key: AMBARI-11542
                 URL: https://issues.apache.org/jira/browse/AMBARI-11542
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: John Speidel
            Assignee: John Speidel
             Fix For: 2.1.0


When provisioning a cluster via the blueprint api, occasionally a database deadlock is detected.  There is retry logic around this code so it doesn't affect the creation of the cluster and a user wouldn't notice this unless they looked at the logs.  That being said, this issue involves incorrect transaction demarcation and synchronization and is potentially serious depending on host it is manifested.
