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.

> Snapshots are point in time images of parts of the filesystem or the entire
> filesystem. Snapshots can be a read-only or a read-write point in time copy
> of the filesystem. There are several use cases for snapshots in HDFS. I will
> post a detailed write-up soon with with more information.
