Suresh Srinivas commented on HDFS-2802: --------------------------------------- bq. I think this is not right. Because it will destabilize branch 2. Dot releases are for bug fixes, not new features. Other dot version did add features. That is how we have significant functionality such quorum journal manager, Automatic failover and many other features. I would like to make snapshots feature available as soon as possible and stabilize a release. > Support for RW/RO snapshots in HDFS > ----------------------------------- > > Key: HDFS-2802 > URL: https://issues.apache.org/jira/browse/HDFS-2802 > Project: Hadoop HDFS > Issue Type: New Feature > Components: datanode, namenode > Reporter: Hari Mankude > Assignee: Tsz Wo (Nicholas), SZE > Attachments: 2802.patch, 2802.patch, HDFS-2802.20121101.patch, > HDFS-2802-meeting-minutes-121101.txt, HDFSSnapshotsDesign.pdf, snap.patch, > snapshot-design.pdf, snapshot-design.tex, snapshot-one-pager.pdf, > Snapshots20121018.pdf, Snapshots20121030.pdf, Snapshots.pdf > > > Snapshots are point in time images of parts of the filesystem or the entire > filesystem.
