>                 URL: https://issues.apache.org/jira/browse/AMBARI-23129
>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.7.0
>            Reporter: Robert Levas
>            Assignee: Robert Levas
>            Priority: Critical
>             Fix For: 2.7.0
>
>
> An NPE is thrown will initializing the Ambari server upgrade catalog:
> {code:title=com.google.inject.persist.jpa.JpaPersistService#begin}
>     public void begin() {
>         Preconditions.checkState(null == this.entityManager.get(), "Work already begun on this thread. Looks like you have called UnitOfWork.begin() twice without a balancing call to end() in between.");
>         this.entityManager.set(this.emFactory.createEntityManager());
>     }
> {code}
> {{this.emFactory}} is {{null}}.
> *Cause*
> {{com.google.inject.persist.jpa.JpaPersistService#start()}} was not called before {{com.google.inject.persist.jpa.JpaPersistService#begin}} to do order of operations in {{org.apache.ambari.server.upgrade.SchemaUpgradeHelper#main}}.  
> *Solution*
> Ensure {{com.google.inject.persist.jpa.JpaPersistService#start()}} is being called before {{com.google.inject.persist.jpa.JpaPersistService#begin}} in {{org.apache.ambari.server.upgrade.SchemaUpgradeHelper#main}}.
