Inigo Goiri commented on HDFS-10629:
------------------------------------

I've been talking to [~subru] about the alignment with YARN-2915 and we saw a 
couple differences. The one that applies to this patch would be the use of 
"resolver" instead of "locator" to follow the same structure as YARN-5390. For 
example,  they have 
{{org.apache.hadoop.yarn.server.federation.resolver.SubClusterResolver}}, so we 
should use here 
{{org.apache.hadoop.hdfs.server.federation/locator/FileSubclusterResolver}. 
[~jakace], do you mind making this change for alignment with YARN federation?

[~mingma], can you take a look at the patch and which comment on which parts 
you would like to be in this patch and which ones for following ones? I think 
we should keep {{Router}} for sure and then based on your feedback decide what 
to add as a basis.
