Kihwal Lee commented on HDFS-10956: ----------------------------------- +1 looks straight-forward. > Remove rename/delete performance penalty when not using snapshots > ----------------------------------------------------------------- > > Key: HDFS-10956 > URL: https://issues.apache.org/jira/browse/HDFS-10956 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: hdfs > Reporter: Daryn Sharp > Assignee: Daryn Sharp > Attachments: HDFS-10956.patch > > > When deleting or renaming directories, the entire subtree(s) is scanned for > snapshottable directories. The performance penalty may become very expensive > for dense trees. The snapshot manager knows if snapshots are in use, so > clusters not using snapshots should not take the performance penalty. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
