Ayush Saxena reopened HDFS-14591: --------------------------------- Reopened and closing again as duplicate rather than fixed. > NameNode should move the replicas to the correct storages after the storage > policy is changed. > ---------------------------------------------------------------------------------------------- > > Key: HDFS-14591 > URL: https://issues.apache.org/jira/browse/HDFS-14591 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Jinglun > Assignee: Jinglun > Priority: Major > > Our Xiaomi HDFS has a cluster storaging both HOT and COLD data. We have a > backgroud process searching all the files to find those that are not accessed > for a period of time. Then we set them to COLD and start a mover to move the > replicas. After moving, all the replicas are consistent with the storage > policy. > It's a natural idea to let the NameNode handle the move. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
