Yiqun Lin commented on HDFS-13219:
----------------------------------

To fix this under shared datanodes case, we may additionally to store all 
existed datanode info in the State Store and do the duplicate removal in 
aggregating summary . Not so sure if this is worth to do.

> RBF:Cluster information on Router is not correct when the Federation shares 
> datanodes.

> Now summary information on Router website aggregates summary of each 
> nameservice. However in a typical federation cluster deployment, datanodes 
> are shared among nameservices. Consider we have 2 namespaces and 100 
> datanodes in one cluster. 100 datanodes are available for each namespace, but 
> we see 200 datanodes on the router website. So does other information such as 
> {{Total capacity}}, {{Remaining capacity}}.
