Yiqun Lin commented on HDFS-15087: ---------------------------------- Hi [~umamaheswararao] and others, I'd like to share current status about HDFS-15294 and maybe some others also want to know this feature. Now [~LiJinglun] almost completed the majority implementation and we are actively working for the one core subtask HDFS-15346. There are still some remaining work like documentation. And after discussed with [~LiJinglun] about this feature design, we are agreed that let this tool become a common balance tool not only used for RBF mode, but also can be used in normal federation clusters. Please share your wonderful thoughts/comments on HDFS-15294 if you are interested in this, :). > RBF: Balance/Rename across federation namespaces > ------------------------------------------------ > > Key: HDFS-15087 > URL: https://issues.apache.org/jira/browse/HDFS-15087 > Project: Hadoop HDFS > Issue Type: New Feature > Reporter: Jinglun > Assignee: Jinglun > Priority: Major > Attachments: HDFS-15087.initial.patch, HFR_Rename Across Federation > Namespaces.pdf > > > The Xiaomi storage team has developed a new feature called HFR(HDFS > Federation Rename) that enables us to do balance/rename across federation > namespaces. The idea is to first move the meta to the dst NameNode and then > link all the replicas. It has been working in our largest production cluster > for 2 months. We use it to balance the namespaces. It turns out HFR is fast > and flexible. The detail could be found in the design doc. > Looking forward to a lively discussion. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
