----------------------------------------
Summary: Storm Shows An Alert for REST_API Component After Stack
Upgrade
Key: AMBARI-10285
URL: https://issues.apache.org/jira/browse/AMBARI-10285
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Priority: Critical
Fix For: 2.1.0
# Upgraded cluster with storm.
# Noticed a CRITICAL alert named "Storm REST API". But there are no REST API
components on stack 2.2. The alert is linking to host with Storm UI Server.
The underlying problem here is that, indeed, Storm REST API was removed on HDP
2.2. However, Ambari doesn't remove the relationships in the database; it just
modifies the in-memory stack definitions.
As a result, the alerts framework still thinks there's a REST_API component
installed on a host. In order to preserve the historical entires for that
component, alerts will determine at startup the definitions which may no longer
be valid and will disable them.
