Imesh Gunaratne commented on STRATOS-1281:
------------------------------------------
Hi Martin,
Thanks for reporting this problem. Logically we cannot remove an application
soon after un-deploying it. The reason is that the un-deployment process
executes gracefully on each cluster, member in the application hierarchy.
Depending on the complexity of the application, it may take some time to
completely un-deploy an application.
IMO what we are missing here is a validation in the delete application API
method, to say the end user that an application cannot be deleted until it is
completely un-deployed.
Thanks

> Stratos 4.1.0 - tracebacks seen when issuing application undeploy/remove
> ------------------------------------------------------------------------
>
> Key: STRATOS-1281
> URL: https://issues.apache.org/jira/browse/STRATOS-1281
> Project: Stratos
> Issue Type: Bug
> Components: Cloud Controller
> Affects Versions: 4.1.0 Beta
> Reporter: Martin Eppel
> Priority: Blocker
> Attachments: wso2carbon.log
>
>
> Hi,
> We are testing the behavior of stratos 4.1.0 rest api's and found that if we
> issue an undeploy-application followed immediately with application-remove,
> that we see the following traceback.
> The VM successfully get's deleted but not sure what kind of side effects this
> has on the system.
> Here's the snippet from the wso2carbon.log file. I've also attached the
> entire log.
> Steps to reproduce this:
> 1) deploy an application which leads to startup a single instance of a
> cartridge.
> 2) wait for it to become active
> 3) issue the undeploy application and application remove rest api calls.
