Rakesh R commented on HDFS-10629:
---------------------------------

Good work, thanks [~jakace] for the patch. It gives an overall idea about the 
{{Router}} service, which provides a unified view of multiple federated HDFS 
clusters.

Adding few quick suggestions and I'll post a full review shortly. It looks like 
the patch is quite big and imho, it would be good to split into 
multiple/smaller logical chunks and push it separately. That would help 
reviewers to focus on specific set of cases and also get chance for better test 
coverage. I could see there is a branch created for this feature. Perhaps we 
could encourage to create patch from that. While uploading/attaching the patch 
to jira, it should be named with the feature branch name so that {{Jenkins}} 
will automatically pick up this patch and run against the branch code. For 
example, {{HDFS-10629-HDFS-10467-00.patch}}
