Subject [jira] [Created] (HDFS-13219) RBF:Cluster information on Router is not correct when the Federation shares datanodes.

Tao Jie created HDFS-13219:
------------------------------

             Summary: RBF:Cluster information on Router is not correct when the Federation
shares datanodes.
                 Key: HDFS-13219
                 URL: https://issues.apache.org/jira/browse/HDFS-13219
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.9.0
            Reporter: Tao Jie


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}}.
