Enis Soztutar commented on HBASE-11484:
---------------------------------------
I think [~ndimiduk] is working on hive support for table snapshot input format.
Restore is a relatively cheap operation, but the IF has to ensure that the
snapshot is restored before being able to read from it. Maybe we can break down
the restore and MR steps and make it useable on their own.
> 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
