Yusaku Sako commented on AMBARI-3999:
-------------------------------------
[~xiwang0309], "hosts" computed property depending on "hosts" is self
referential. I suppose Ember is OK with it but this seems a bit odd.
Also, a computed property should not have side effects (as opposed to
observers).
A cleaner fix might be to define the displayName computed property for the host
object itself, or make an observer to set the displayName.
> Long host names are inconvenient for viewing in background operations popup

> Result:
