[jira] [Created] (AMBARI-20894) Setting Desired Stack Ids to
Correct Values During Service and Patch Upgrades
Jonathan Hurley created AMBARI-20894:
----------------------------------------
Summary: Setting Desired Stack Ids to Correct Values During Service and Patch Upgrades
Key: AMBARI-20894
URL: https://issues.apache.org/jira/browse/AMBARI-20894
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: trunk
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Priority: Critical
Fix For: trunk
During a {{PATCH}} or {{SERVICE}} upgrade, only the desired stack IDs of the service/components being upgraded should be updated. Currently, it is observed that:
- {{hostcomponentdesiredstate}}/{{desired_stack_id}} is updated for all components
- {{servicedesiredstate}}/{{desired_stack_id}} is updated for all services to new stack
However, the {{hostcomponentstate}} table has the correctly values for {{version}} and {{stack_id}}.
h5. Example Upgrade of {{STORM}} from HDP 2.4 to HDP 2.5
h6. Topology
- c6401 - ZooKeeper Server, ZooKeeper Client, Storm Nimbus
- c6402 - ZooKeeper Server, ZooKeeper Client, Storm Supervisor
- c6403 - ZooKeeper Server, ZooKeeper Client, Storm Supervisor
