----------------------------------------
Summary: Ensure upgrade request is un-affected if there exists a
stage with no tasks
Key: AMBARI-13934
URL: https://issues.apache.org/jira/browse/AMBARI-13934
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: 2.1.2
Reporter: Siddharth Wagle
Assignee: Siddharth Wagle
Fix For: 2.1.3
When you delete a host, it will delete all associated host_role_commands.
During upgrade, if a host is deleted, then it is possible to have a Stage
within the Upgrade request to have no tasks. Verify that it does not affect the
upgrade operations.
Possible issues:
* A stage with no tasks should be declared as COMPLETED if not then it may
result in the failure of the request
* Some host_role_command (tasks) may be read once and then cached. Such cache,
if they exist need to be refreshed
