Chris Douglas commented on HADOOP-12185:
----------------------------------------

I haven't looked at the context at all, but is there any reason to retain both 
the List and the Map? Wouldn't it be sufficient to look at 
{{childrenMap.values()}} for any context requiring the List?

> NetworkTopology is not efficient adding/getting/removing nodes

> NetworkToplogy uses nodes with a list of children. The access to these 
> children is slow as it's a linear search.
