Summary: Unable to Begin An Upgrade Between Stack Versions Due To Assumed Stack Names 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
