Description
With HBase 0.98, HBase now supports MR over HBase snapshots instead of active tables.[1] This looks to have significant performance impacts. One thing that will be different about this sort of I/O is that we will probably not have "target" support but instead only Source. HBase snapshots do a lot with how the files are stored/tracked such that it wouldn't really make sense to support generating a snapshot.
