Subject Re: What is the correct way of undeploying application and remove runtime/instances
Date Thu, 18 Dec 2014 17:46:31 GMT
Hi Udara,

I have fixed the flow in ff9379f66cd5c66dfa3bcba42df4c949407f2883. With the
same undeploy application command, application runtime will get removed
after wiping out the members of the clusters. Now i could undeploy
the application and deploy the same again without any issue.

Thanks,
Reka
