Jing Zhao updated HDFS-2802: ---------------------------- Attachment: snapshot-testplan.pdf Upload the current test plan. We followed this test plan and tested the existing snapshot functionalities (except rename and concat) in a small cluster with 5 nodes for a week. The tests we have done include 1) the basic operation test, 2) the long-running test, and 3) the stress test described in the test plan. Currently the tests run well and the snapshot functionality seems stable. Several bugs have been caught and we have filed HDFS-4616, HDFS-4627, HDFS-4636, and HDFS-4637 for fix. We will continue running the tests and fixing bugs. > 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.diff, 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, snapshot-testplan.pdf > > > Snapshots are point in time images of parts of the filesystem or the entire > filesystem.
