Subject [jira] [Commented] (STRATOS-1281) Stratos 4.1.0 - tracebacks seen when issuing application undeploy/remove
Date Fri, 27 Mar 2015 18:16:53 GMT

    [ https://issues.apache.org/jira/browse/STRATOS-1281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14384282#comment-14384282
] 

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
Imesh

>    Affects Versions: 4.1.0 Beta

> 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.
