Reinitialize ambari-web application

[Thibaut Marmin <tm...@cyres.fr>]

Hi everyone,

I'm trying to to implement a way to manage multiple clusters from single ambari web interface. I never worked with ember framework so I try to understant gradually.

I'm able to modify template (to add clusterName field to the login form), implement modifications in controllers, routes etc. In this first implementation, if you want to switch to another cluster, you have to sign out and log in again with another cluster name.

Everything works except one thing. I still have a problem with Ember datastore which is not fully reloaded for each login step. It makes that when I login with another cluster name, previous service name and hosts (inter alia) still displayed.

When user logs out, I could remove each items related to the current cluster stored in App.store, but I don't know if it is the best way. -> App.store.findAll(App.[MODEL]).forEach(function(item){item.deleteRecord()})

I'll suggest a patch for issue 1518 if I found an appropriate solution.

Thanks.

Thanks for your answer.

In this quickly realized patch, I added a cluster name field to the login form. So a new clusterName attribute is stored in App.db (as the login name). The clusterController has a new method isSync used to check if current cluster is the same as expected one.

Currently I failed to reload full cluster (I should clean the Model) so I added a hack which reloads window on logout (window.location.reload(true)).

Sorry if my code is not perfect, I'm new on the project..

Hi Thibaut,

Can you attach your patch, even if it's work-in-progress, to AMBARI-1518?
That makes it easier to suggest solutions.
