> Key: AMBARI-21346
> URL: https://issues.apache.org/jira/browse/AMBARI-21346
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.5.2
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Blocker
> Fix For: 2.5.2
>
>
> When attempting to begin an upgrade between stack versions from different
> vendors (ie HDP and BigInsights), various steps will fail because the Ambari
> Server code assumes that the stack name is not changing. Therefore, actions
> like finding the right upgrade pack will fail with a NullPointerException
> {code}
> java.lang.NullPointerException
> at
> org.apache.ambari.server.state.UpgradeContext.setSourceAndTargetStacks(UpgradeContext.java:277)
> {code}
> We can work around this temporarily by falling back to querying by the
> version number directly.
