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. > -------------------------------------------------------------------------------------- > > Key: HDFS-13219 > URL: https://issues.apache.org/jira/browse/HDFS-13219 > Project: Hadoop HDFS > Issue Type: Sub-task > Affects Versions: 2.9.0 > Reporter: Tao Jie > Priority: Major > > 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}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
