-----------------------------------------
Summary: Web Client Should Warn On Host Version Mismatch For
Maintenance Mode
Key: AMBARI-12973
URL: https://issues.apache.org/jira/browse/AMBARI-12973
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.1.2
Reporter: Andrii Babiichuk
Assignee: Andrii Babiichuk
Priority: Critical
Fix For: 2.1.2
After a stack upgrade, if a host is brought out of maintenance mode it will
begin to report versions for its components which don't match the stack . The
current behavior today will mark this host as being "out of sync" with the
current stack. When bringing a host of out maintenance mode, the web client
should check versions of the components on that host. If they do not match the
cluster's current stack, a warning should be presented to the administrator.
Once the host is brought out of maintenance mode, if its component versions are
different, the stack will be marked out-of-sync as it is today.
