Lohit Vijayarenu commented on HADOOP-3637:
------------------------------------------

Does this mean, we can get rid of SecondaryNameNode and use it only for failovers?

> Support HDFS snapshots. It should support creating snapshots without shutting down the
file system. Snapshot creation should be lightweight and a typical system should be able to
support a few thousands concurrent snapshots. There should be a way to surface (i.e. mount)
a few of these snapshots simultaneously.
