dhruba borthakur commented on HADOOP-1933:
------------------------------------------

I would like all hosts in the includes and excludes file to be displayed in the 
web-ui. The hosts in the excluded list would probably show up in the "Dead node 
list".

> Consider include/exclude files while listing datanodes.

> While listing datanodes (e.g. in webui), consider the nodes listed in include 
> and exclude files.
> Proposed Rules :
> # If a node is listed in include file, it should be listed
> # If a node is listed under exclude file, it should not be listed unless it 
> is not 'dead'.
> Dhruba implies only the first rule applies towards the end of HADOOP-1138, 
> i.e., a node should be listed if it exists either of the files. Dhruba, 
> please clarify.
