Antonenko Alexander commented on AMBARI-4088:
---------------------------------------------
Solution that we discussed with Yusaku Sako is to show spinner with overlay
that will block that part of screen, till all hosts will be loaded.
> UI doesn't select all hosts on Assign Slaves step sometimes

> Key: AMBARI-4088
> URL: https://issues.apache.org/jira/browse/AMBARI-4088
> Project: Ambari
> Issue Type: Bug
> Components: client
> Affects Versions: 1.4.2
> Reporter: Antonenko Alexander
> Assignee: Antonenko Alexander
> Priority: Critical
> Fix For: 1.4.3
>
>
> When deploying large cluster (>600 nodes) UI not always selects all hosts on
> assign slaves step.
> For example on last reproduce, it selected only 336 of 600 expected slaves.
> Actually theres workaround, on review step you can see that there's less
> slaves then expected and return to assign slaves step, but then you have to
> repeat all following steps.
> It looks like select event is triggered earlier then all host rows loaded as
> unselected hosts are always last ones.
