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}}.
