Wei-Chiu Chuang commented on HDFS-15087: ---------------------------------------- Great work here. Sorry I didn't realize. Mind if I make this a "New Feature"? This is significant amount of change that I think it makes a new feature. > 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
