> h6. hbase shell with snapshot commands
> * snapshot <snapshot name> <table name>
> ** Take a snapshot of the specified name with the specified name 
> * restore_snapshot <snapshot name>
> ** Restore specified snapshot on the original table
> * clone_snapshot <snapshot name> <table name>
> ** Create a new table based on the snapshot content
> * list_snapshots [filter]
> ** Show the list of snapshots taken
> * delete_snapshot <snapshot name>
> ** Remove a specified snapshot
> * rename_snapshot <snapshot name> <new snapshot name>
> ** Rename a snapshot to a new name
> h6. Restore Table
> Given a "snapshot name" restore override the original table with the snapshot content.
> Before restoring a new snapshot of the table is taken, just to avoid bad situations.
> This allows a full and quick rollback to a previous snapshot.
> h6. Clone from Snapshot
> Given a "snapshot name" a new table is created with the content of the specified snapshot.
> This operation allows:
>  * To have an old version of the table in parallel with the current one.
>  ** Look at snapshot side-by-side with the "current" before making the decision whether
to roll back or not
>  * To Add/Remove data from this table without affecting the original one or the snapshot.
>  * To Restore only "individual items" (only some small range of data was lost from "current")
>  ** MR job that scan the cloned table and update the data in the original one. (Partial
restore of the data)
> h6. Open points
>  * Add snapshot type option on take snapshot command (global, timestamp)?
