deepankar commented on HBASE-11484:
-----------------------------------
[~mbertozzi] Are you suggesting to remove this step of RestoreSnapshot entirey,
by having a constructor or openRegion method which takes a manifest? Seems a
very good idea, I can take this up if you are okay with it?
[~ndimiduk] Sure will take a look at the jira and will contribute if i can.
> Provide a way in TableSnapshotInputFormat, not to restore the regions to a
> path for running MR every time, rather reuse a already restored path

> We are trying to back a Hive Table by the Map Reduce over snapshots and we
> don't want to restore the snapshot to a restoreDir every time we want to
> execute a query. It would be nice if there is boolean in the function
> *TableSnapshotInputFormat.setInput* and exposed outside in the
> *TableMapReduceUtil.initTableSnapshotMapperJob*, with this boolean
> it will check whether the snapshot and the restore dir are in sync, rather
> than restoring again.
> Is this Idea looks Ok to you guys or you have any other suggestions, I will
> put up a patch for this if this idea is ok for guys
