----------------------------------------
Summary: Pre-Req Checks Should Only Warn On Unhealthy Slave Hosts
Key: AMBARI-12903
URL: https://issues.apache.org/jira/browse/AMBARI-12903
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.0
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Priority: Critical
Fix For: 2.2.0
During the prerequisite checks, any of the existing checks that prevent the
upgrade from starting based on stack distribution or host availability will
need to be modified to exclude unhealthy hosts.
A new prerequisite check will also be created to warn the administrator that
there are hosts which are in maintenance mode and will not be upgraded. This
warning is for informational purposes only and will not stop the upgrade.
