Chris Nauroth commented on HDFS-2802:
-------------------------------------
I just want to drop a quick note about Windows compatibility for snapshots.
I've done a full test run of all snapshots tests on Windows. Out of all those
new tests, only 1 failed! It was {{TestNestedSnapshots#testSnapshotLimit}}.
It failed on test timeout while trying to create 2^16 snapshots. I suspect the
failure is just due to poor performance on my VM rather than a Windows
compatibility concern. If so, then this is easily fixed by tuning the test
timeout. Nice job everyone on implementing a major new feature without
accidental platform dependencies!

> 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.
