Nick Dimiduk commented on HBASE-11484:
--------------------------------------
Hi [~dvdreddy]. The work on adding support for Hive is happening on HIVE-6584.
If you have design and use-case comments, please add them over there. It looks
like the patches may need a refresh though. We can also accommodate HBase
improvements as necessary.
>From the perspective of my contribution, I was planning to abstract away the
>restore directory from the Hive user once I have a working implementation.
>Patches welcome ;)
> Provide a way in TableSnapshotInputFormat, not to restore the regions to a
> path for running MR every time, rather reuse a already restored path

> Project: HBase
> Issue Type: New Feature
> Components: mapreduce
> Reporter: deepankar
> Priority: Minor
>
> 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
