Summary: Web Client Does Not Display Errors When Creating Upgrade
Key: AMBARI-14207
URL: https://issues.apache.org/jira/browse/AMBARI-14207
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.2.0
Reporter: Xi Wang
Assignee: Xi Wang
Priority: Critical
Fix For: 2.2.0
Attachments: popup.png
When creating an upgrade, an HTTP error returned (such as a 500 error) is never
propagated up to the end user.
STR:
- Setup a 4-host cluster with ZK, Yarn, HDFS
- Install clients only on the 4th host
- Place the 4th host into maintenance mode
- Start an upgrade
The server will correctly throw an exception since service checks cannot be
scheduled since 4th host in maintenance mode is excluded. The error is
propagated up as an HTTP 500 error:
{code:title=HTTP/500}
While building a service check command for YARN, there were no healthy eligible
hosts: unhealthy[], maintenance[c6404.ambari.apache.org]
{code}
This message should be shown to the end user. Otherwise, nothing happens in the
UI and there is no indication of an error.
