---------------------------------------
Summary: Some times (rarely) login page does not load when sign out
Key: AMBARI-14322
URL: https://issues.apache.org/jira/browse/AMBARI-14322
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.2.0
Reporter: Sandor Magyari
Assignee: Sandor Magyari
Priority: Critical
Fix For: 2.2.0
This issue is reproducible in case when before clicking Sign out you will send
many requests to server. This can be achieved by switching between different
application sections that invokes a lot of GET requests.
I attached two videos one with normal sign out, and one that is showing this
issue.
Here is what is happening:
Click on Sign out button invokes the following request:
URL: api/v1/logout
response status code: 200
After this UI redirects to root of the site (http://HOST_IP:8080/)
and to understand if we are logged in UI makes the following request:
URL: api/v1/clusters?fields=Clusters/provisioning_state, the response on this
request with 403 error will lead us to http://HOST_IP:8080/#/login page, and
response status 200 we treat as user is logged in and redirect him to
#/main/dashboard/metrics.
The root case of this issue is that when we spam server with request and try to
sign out calling call api/v1/logout, it actually does not logout on server
because later when we call api/v1/clusters?fields=Clusters/provisioning_state
we receive response with status 200 like user us still logged in.
UI hangs later, because when we were doing logout stuff, we dropped different
properties thinking that we will be logged out. This inconsistency in data
between UI and wrong server response
api/v1/clusters?fields=Clusters/provisioning_state leads to such unpredictable
behavior.
